The War Games ( TV story ) The War Games was the seventh and concluding story of the sixth season of " Doctor Who " . It was the final story of the 1960s and the last produced in monochrome . It was notable for introducing the Time Lord s and for being the first time that the Doctor ' s home planet was seen . It was also the first story in which Derrick Sherwin was credited as producer . Discounting " The Trial of a Time Lord " as four narratively linked stories , it was the longest " Doctor Who " story to survive the purging of the BBC ' s videotape archive and currently marks the earliest point in the series where first - time viewers may begin watching " Doctor Who " in chronological order without encountering any missing episodes . It was also the first story to have a large gap of time between it and the next one . The final episode saw the departure of Patrick Troughton as the Second Doctor and Frazer Hines and Wendy Padbury as companion s Jamie McCrimmon and Zoe Heriot . It was the first time in the history of " Doctor Who " that either a companion or an incarnation of the Doctor made their last regular appearance in the concluding episode of a season . It was also the first time that an incarnation of the Doctor and all his companions were written out of the program in the same story . The story also featured a father and son playing roles on screen : David Troughton , the son of Patrick Troughton , appeared in this story . Synopsis . The Doctor , Jamie and Zoe arrive on an unnamed planet . At first believing themselves in the midst of World War I , they realise it to be one of many War Zones overseen by the War Lord s , who have kidnapped large numbers of human soldiers in order to create an army to conquer the galaxy . Infiltrating the control base , the Doctor discovers that the War Chief is also a member of his own race . The creeping realisation sets in that the Doctor cannot solve this problem alone , and that his days of wandering may be at an end . . . Plot . Episode one . The TARDIS lands in a desolate wasteland on Earth . The crew laugh as Jamie leaves the TARDIS and treads directly into a puddle . As they explore , they see barbed wire , and the discovery of a pith helmet allows the Doctor to place them in history . Bombs start to fall , and the crew duck for cover . They are surprised when they are confronted by a woman . She says that they need to get to safety . She is heading to Ypres . They encounter soldiers who lead them away . The woman is driving the soldiers , the Doctor and Jamie across No Man ' s Land in an ambulance when they are met by a lieutenant . He asks to be taken back to base . In a trench , a major is told that an ambulance is coming in . He orders protective fire . The passengers clamber into the trench . The lieutenant , by the name of Carstairs , tells the major about the civilians found in No Man ' s Land . Outside , the Doctor is explaining trench warfare to Jamie . They decide to escape but are stopped by Carstairs . They are summoned to see the major . Major Barrington gets word from General Smythe that they are to go over the top tomorrow . The Doctor , Jamie and Zoe enter alongside the ambulance driver who introduces herself to Barrington as Lady Jennifer Buckingham . The major casts his eye over the civilians . He suspects Jamie to be from the Highlander regiment and says that war is no place for a young woman like Zoe . He starts to suspect they may be spies and contacts General Smythe . Smythe asks for the civilians to be sent to him . He moves into an adjoining room and begins to pull back a picture . He is interrupted by a soldier who he shouts out . When alone he pulls back the picture to reveal a communications device . He states that the " reinforcements are acting quiet " and that there are " at least 5000 specimens " . Barrington orders the Doctor , Jamie and Zoe to go . Jamie loses his temper and shouts at him , and guns are drawn . The Doctor states they had better go . Barrington says they will fix Jennifer ' s ambulance . Carstairs says he does not hold much hope for the Doctor , Jamie and Zoe as Smythe has the nickname of " the Butcher " . The Doctor , Jamie and Zoe are marched into Smythe ' s room . Jamie is still complaining . Captain Ransom goes to get Smythe but finds him not in his room . Ransom , flustered , orders them to be taken to the cells . Jennifer and Carstairs talk . They both are experiencing memory issues . They put this down to the ravages of war . Barrington tells them that they are all wanted at headquarters . Jamie and Zoe inspect the cell . There is no way out . Smythe emerges from his room . Confused , Ransom tells him that the civilians are here and that he came to tell him but he wasn ' t there . Smythe puts on his glasses and says that he was sleeping and that Ransom didn ' t want to disturb him . Blindly , Ransom agrees . Barrington , Jennifer and Carstairs enter . Smythe insists that Carstairs and Ransom know each other . They seem unsure . Smythe puts the glasses on and says they went to school together . They both instantly agree . Later that day the Doctor , Jamie and Zoe are brought into Smythe ' s room . He reads the crimes alleged against them . He states they waylaid the ambulance to get into the trenches and that they were attempting to escape back to the Germans with information . Jamie is charged with desertion while Zoe and the Doctor are charged with espionage , all crimes that carry the punishment of death . The Doctor asks if he can cross examine Carstairs and Jennifer . Smythe agrees but closes down all lines of questioning . They are marched away . Barrington and Ransom both seem to think there is not enough evidence to convict them . Smythe puts on his glasses and says they are obviously guilty . They concur . The Doctor , Jamie and Zoe are marched back in and told they are guilty .

A Redcoat is thrust into prison with Jamie . He is scared and doesn ' t know how he got there . He thinks it is 1745 . The Doctor is spying on the military prison through a telescope . He commandeers a military vehicle and acts like it was sent for him . A bemused soldier drives him into the prison . Jamie questions the Redcoat . The Redcoat remembers stumbling into some mist and then , when it cleared , finding himself flanked by big guns and horseless carts . He was then brought to the prison . He is distrustful of Jamie . Commandant Norton is disturbed from his tea by the Doctor , who pretends he is from the War Office and has been sent to inspect the prison . Zoe is his secretary .

He and Carstairs go to look for him whilst Jennifer stays at headquarters . The Redcoat and Jamie are fighting . When the soldiers come in to break them up , they turn on them and escape . Carstairs returns , having found nothing . Jennifer says she has started to remember getting lost in some mist before finding herself here . Carstairs wonders if it is a new gas . Norton is showing the Doctor the plans of the prison . He asks to talk to a prisoner . Norton receives a phone call to say that a Scotsman and a Redcoat have escaped .

Carstairs enters . Jennifer questions Ransom as to whether Smythe often disappears at the drop of a hat . Ransom shrugs it off and is about to go and inspect the prisoners , before Jennifer engages him in conversation to stall him . The Doctor , Jamie and Zoe have explained the existence of the video screen to Carstairs . He says he will accompany them to Smythe ' s quarters and they can show him . Ransom is still talking when the phone rings . Carstairs tells Jennifer to decoy Ransom . Jennifer says that the phone call was from Smythe and that he wants Ransom to meet him in the furthest sector . Ransom leaves just as Carstairs ' party arrives . They go into Smythe ' s room , and Zoe swings back the picture to show them the screen . Carstairs and Jennifer can ' t see it . The Doctor implores them to concentrate and it emerges . In another location , Smythe is watching them uncover his secret . The Doctor realises that the control is receiving and they all need to run . Carstairs and Jennifer relent eventually . Jennifer goes to get the ambulance . Jamie wants to go back to the TARDIS but the Doctor and Zoe overrule him . They are about to leave when Ransom emerges . Carstairs says that Smythe has asked the prisoners to be moved . Ransom queries the order due to the fact he was sent on a wild goose chase , but he eventually relents , fearful of the wrath of Smythe . They all clamber into the back of the ambulance and move off . In Smythe ' s quarters , the unit materialises , and Smythe emerges . Smythe questions Ransom as to the location of the prisoners and is furious when Ransom says he has let them go . Ransom sees that the ambulance has gone , and Smythe issues a general order for it to be located . Later , the ambulance has been spotted , and Smythe orders for artillery to be used on it . Ransom questions if they should be killing two women and a member of their own army . Smythe puts his glasses on and orders it . Ransom agrees . Carstairs takes cover in the ambulance as shells land around them . The Doctor joins Jennifer in the front of the ambulance , and they drive off into some mist . The ambulance disappears . Jennifer becomes scared as the mist encroaches . The ambulance emerges . The Doctor thinks the mist is some kind of force field as they are no longer surrounded by war or guns .

Carstairs desperately tries to restart the ambulance as the chariot approaches . Episode three . As the Romans approach , Carstairs gets the ambulance going , and they reverse back into the mist and disappear , leaving the Romans dumbfounded . The ambulance re - emerges back in 1917 . The Doctor theorises that the mists act as barriers between different time zones and further theorises that there must be a map setting these out . They head back to Smythe ' s headquarters to uncover the map . Carstairs returns as if he has the rest of the group prisoner . Ransom doesn ' t fall for it , and Carstairs pulls his gun on him . Jamie removes Ransom ' s gun . He is trussed up with bandages . The Doctor sets about looking for the map . In Smythe ' s room , he finds a safe . He attempts to pick the lock whilst Carstairs seeks explosives to blow it open . Carstairs returns with a Mills Bomb — a type of grenade . Seeing that the whole bomb would destroy the room but not the safe , the Doctor takes the explosive out of the bomb and places it in the lock , extending the fuse with a candle wick . Ransom frees his mouth from the gag and calls for help . Carstairs goes out to address this , and once he has silenced him , a soldier , drawn by the noise , comes with Zoe and Jennifer in tow , looking for Ransom . In Smythe ' s room Jamie and the Doctor light the fuse and take cover . Carstairs is trying to get rid of the soldier but he is happy to wait for Ransom . He questions Carstairs as to who he is and where he has come from . The Doctor and Jamie hear the conversation outside and start to panic . The soldier is convinced and starts to leave but takes his time . The Doctor wants to put the fuse out but it ' s too late . As the soldier closes the door , the explosion rings out around the headquarters . He returns and rushes into Smythe ' s room . Carstairs pulls a gun on him , and Jamie trusses him up . The Doctor has found the map . In the centre is a blank space . That is where they should go . They head off in the ambulance but are soon surrounded by German soldiers .

He asks Zoe where she met the Doctor . The Doctor orders her to tell the truth . She says she met him at a space station . He asks Jamie when he met the Doctor , and he responds by saying he met him in 1745 . The soldier is still unconvinced . The Doctor shows him the sonic screwdriver . He removes a screw from the soldier ' s gun and returns it . The soldier is starting to be convinced . A superior by the name of von Weich enters . The soldier tells him what he has discovered . Von Weich and the soldier withdraw . Von Weich puts on a monocle and tells the soldier that they are not time travellers , they are spies and should be shot . The soldier returns and tells the Doctor , Jamie and Zoe that they are spies and should be shot . Von Weich pulls back a picture in his quarters to reveal a communications screen . He reports the capture of the Doctor , Jamie and Zoe . The Doctor protests with the German soldier . He reminds him of the sonic screwdriver and displays it again . The soldier starts to remember , but as he does the Doctor steals his gun and holds him up . He orders that they be taken back to their ambulance . In a central HQ , an alarm sounds .

The Doctor and his colleagues have arrived in 1862 America — the Civil War . Their ambulance is beset by gun shots . Carstairs returns the fire , and they move off . The Doctor is pleased . He believes that if they are in the American Civil War zone , they are on the right track to the blank space . The ambulance is stopped by a felled tree . Carstairs gets out to investigate and calls for Jamie to help move it . As they start , they are ambushed by soldiers . Carstairs starts firing at the soldiers as the Doctor , Jamie and Zoe move the tree . Carstairs engages in hand - to - hand battle with a soldier as Jamie comes to help him .

Episode four . Jamie and Jennifer are soon surrounded by soldiers . The Doctor and Zoe look around the ship . Zoe notes it looks exactly like the TARDIS . She asks the Doctor who else could possess a ship like that . The Doctor has one idea but hopes he is not right . Zoe finds some goggles on the side . They begin to explore . They find a room filled with stationary dormant German soldiers in some kind of trance . In another room , there is a fleet of Romans in the same state . The ship starts to land . The door opens , and the Romans leave . Zoe wants to escape , but the Doctor says they will just end up in another war zone . They must wait until it returns to its base . The soldiers question Jamie and Jennifer . When they realise that they are English , they assume they are spies from the South and tie them up . As soon as they are tied up , there is an attack . In the battle , the soldiers retreat from the barn , and Jamie and Jennifer are liberated by Northern forces . One of the soldiers reports to their general . It is Von Weich . He puts his monocle on and says that they are spies and should be tied up . The War Chief berates a scientist on the 5 % of their soldiers who are breaking their processing and causing pockets of resistance . He is fearful that they will form a rebellion . The scientist says they have already come up with a stronger form of processing . An alarm sounds . Von Weich reports via video screen that Jamie and Jennifer have been found , but the Doctor and Zoe are still loose . The War Chief states they will be excellent specimens for re - processing . The machine is landing . The ship is empty , so the Doctor states that it must be back in its base . He notes that the ship is powered by remote control but also has some kind of manual controls .

When the soldier returns , Jamie dismounts him and steals his horse . The soldier tries to shoot him as he rides away . The Doctor and Zoe are exploring . The building has a reception area , living quarters and lecture rooms . They reckon it is some kind of training school . They are ushered into a hall , being told they ' re late for the lecture . The scientist explains how for years soldiers have been removed from their real world and time , processed to forget their previous life and placed in false wars made to look like their home time . Of late , specimens have been breaking their processing and forming resistance groups , but they have come up with a better form of processing and will prove it on a difficult specimen . Carstairs is brought out . He sees the Doctor , but he tells him to keep quiet . The scientist prepares the equipment . Zoe wants to help , but the Doctor says they will help later . Carstairs is brainwashed into thinking the lecture hall is the officer ' s mess in the trenches . He spots the Doctor and Zoe again and says they are German spies . Jennifer is pursued by a soldier . She falls , and he dismounts . As he looms over her , Jamie rides up and fights the soldier . Before they can escape , they are captured , yet again , by soldiers . Carstairs is restrained as he rages about the German spies and the court martial . The Doctor feigns sympathy with the scientist for the failure of his machine . The scientist doesn ' t consider it a failure . The Doctor suggests that the issue was probably that Carstairs should have been fully deprocessed before attempting the reprocessing . The Doctor doubts that the scientist ' s machine could do that . The scientist puts him right and shows him how he would do that . Jamie , Jennifer and Harper , the soldier that liberated them , are returned to the barn and tied up . The soldier explains the resistance to Jamie and Jennifer .

Von Weich is a prisoner to the Resistance . Jamie is informed that they are waiting for their leader , Russell . Harper , the soldier that has been helping Jamie and Jennifer , questions Von Weich as to where the tunnel is that new recruits emerge from . Jamie tells him that it is not a tunnel but instead a craft . Harper doesn ' t believe him . Another soldier wants to leave and move on . He wants to shoot Von Weich . He and Harper get into a fight that is broken up by the arrival of Russell . As Russell brings order to the barn , Jamie sees Von Weich unveiling a monitor . Jamie grabs him and exposes the monitor , saying it backs up what he was saying . Zoe is brought into a room where she is interrogated by the Security Chief . He puts a helmet on and aims an eyepiece at Zoe . This causes her to instantly tell the truth . When she cannot answer when she joined the Resistance and when she gives the answer that she is from the 21st century , the Security Chief is confused . He asks her how she got here , and she explains all about the TARDIS and the Doctor . The Security Chief beams photos into her head , looking for her to identify the Doctor . The Doctor stumbles into the scientist who has Carstairs tied up . When the scientist begins to question why the Doctor is here when there is a security alert out for him , the Doctor convinces him that it was Zoe who the alert was out for and not him . The scientist is about to begin the deprocessing , and the Doctor asks if he can stay and watch . He enquires if Carstairs will remember everything . The scientist confirms he will . The scientist asks the Doctor to strap Carstairs in . The Doctor only pretends to . Once the deprocessing has taken place , Carstairs remembers the Doctor . Seeing this , the scientist tries to grab the Doctor . The Doctor forces the scientist into the deprocessing machine and turns it on . The Doctor explains to Carstairs what has been going on before they escape , turning the machine down before they go to allow the scientist to simmer . Jamie and Jennifer explain the situation to Russell . As they do , Von Weich lurches forward and sets off an alarm . In headquarters the alarm resonates and there is no response . The Security Chief reports to the War Chief that Zoe cannot recognise any of the Resistance members . Zoe is unconscious . The Security Chief lies and says that Zoe is from 1917 and omits anything to do with the TARDIS . The War Chief is informed of the alarm . The War Chief and the Security Chief go to investigate , narrowly missing the Doctor and Carstairs in the corridor . The Doctor bursts in , taking the armed guard by surprise . As the Doctor distracts him , Carstairs knocks him out . Zoe wakes up and informs the Doctor of what has happened . The Doctor tries the helmet on and sees all the Resistance members . He speculates that if they could mobilise all of them at the same time , they could form an army to rise up against their controllers . When Carstairs asks how they get back , the Doctor responds by saying they will leave by the same way they came . There is still no response from the American Civil War Zone . The Security Chief decides to send guards . An alarm goes off as the Doctor , Zoe and Carstairs move through the corridor . They hide and wait until the guards move off before following them to the landing bay . They see the machine land . Back at the barn , everyone is speculating as to what the alarm portends . Jamie thinks they will send a machine . No sooner has he said this then the sound of dematerialisation rings out . They all hide . As the guards emerge , the soldiers spring an attack on them . They are captured , but Harper is killed . Russell is dumbfounded by the futuristic guns used by the guards . They all study the machine . Back at headquarters , the War Chief is cross at the Security Chief for his continual mistakes . The Security Chief questions as to how the War Chief recognised the Doctor . The War Chief reacts furiously to being questioned . He states that when he came to the Security Chief ' s people , he was promised safety and organisation . He reminds the Security Chief that without his knowledge none of this would be possible . The Security Chief says that if the War Chief has any complaints , he should go to the War Lord . The War Chief says he will and sends the Security Chief away to continue the interrogation of Zoe . The Security Chief returns to find the soldier prostrate on the floor and Zoe escaped . Jamie is still trying to convince Russell as to the value of the machine . Russell asks Von Weich , but he refuses to answer . Jamie gives up and decides to get into the machine without anyone ' s help . Jennifer initially says she will go with him but is convinced against this by Russell , who says that he has many sick soldiers she can tend to . Russell and some of his men will go instead . The door is closing , and they hurry in . As the machine dematerialises , Von Weich seems very happy . The Security Chief finds the scientist and liberates him from the deprocessing machine . The scientist explains what happened and says he must report it to the War Chief . The Security Chief stops him and confides with him that Zoe and the Doctor are time travellers . The scientist states that only the War Chief and his people know of time travel . The Security Chief states that the War Chief is a traitor to his own people — how can they be sure he is not a traitor to them ? The War Chief is told that the transport is returning but hasn ' t radioed in as per protocol . The War Chief decides to deal with this himself and sends guards down to the landing bay . The Doctor , Zoe and Carstairs are still in hiding in the landing bay , waiting for the return of a machine . They hear the alarm go off . At the same time , the light that signals the arrival of the machine flashes . Many guards pile into the landing bay . As the machine lands , Jamie and the soldiers emerge . They are all shot by the guards . Episode six . Zoe is fearful for Jamie , but the Doctor states that there is nothing that they can do . They run off , heading to the processing room . The Security Chief and the scientist talk about how the Doctor and Zoe are different to the resistance fighters and that they were not brought from their own time but instead came of their own accord . The Security Chief is worried that the War Chief is either bringing his own people , the Time Lord s , there or they are coming of their own free will . The scientist says that the Security Chief should tell the War Lord , but the Security Chief needs proof . He implores the scientist to bring him any unusual specimens he finds amongst the resistance fighters . The Doctor , Zoe and Carstairs find the way to the processing room heavily guarded . The Doctor tries to find another way . He discovers that the walls are embedded with metal and are held together using a force field . He sets about reversing it with tape . On the other side of the wall , the scientist is examining the resistance fighters they ambushed in the landing bay . The Doctor uses his sonic screwdriver for power to operate his force field reverser . Initially it seems as if it has had no effect , but the Doctor approaches a lane and just lifts it away . They see Jamie being lifted onto the reprocessing machine . The scientist analyses Jamie ' s brain and finds the pattern different to the other resistance fighters . He sends him away to the Security Chief but is interrupted by the War Chief , who questions him as to why he is being taken away . The scientist tries to lie , but the War Chief scares the truth out of him . He allows it to go ahead . This is all watched by the Doctor , Zoe and Carstairs . Once the War Chief has left , Carstairs enters the room and silently disables a guard . The Doctor surprises the scientist as he tries to help him with the machine . Back in the barn in 1917 , Von Weich is being guarded by a young soldier called Moore . He asks for some water . As Moore fetches it , Von Weich tries to escape . Moore stops him just in time . The Security Chief is questioning Jamie with the helmet on . He asks who sent the travellers here — Jamie says no one . He asks why they decided to come here — Jamie explains the TARDIS ' malfunctioning controls . He asks if they were summoned — Jamie replies in the negative . The interrogation is interrupted by the War Chief . They argue . The Security Chief makes it clear he mistrusts the War Chief . The War Chief says if he has a problem he should go to the War Lord , but if he gets his facts wrong he will crush him . The Doctor has resurrected the resistance fighters . A guard comes across the room , and Carstairs kills him . They flee through the hole in the wall . The Doctor endeavours to take the reprocessing unit with him but is forced to abandon it when more guards arrive . The Doctor fills Russell in . The plan from here is to return to their time zones and bring the resistance fighters together to form one big army . They head off to the landing bay . . . but need a disguise first . Von Weich asks Moore if he could put his monocle in . When he obliges , Von Weich brainwashes him into thinking it is 1871 and that he is Moore ' s commanding officer . He orders himself untied . The Security Chief brings the War Chief to the processing room and discovers his prisoners gone . He says this is proof positive that they have a space / time machine . The War Chief finds the hole in the wall and dismissively sends the guards to the landing bay . Jamie wakes up and is shocked to see a gas mask in front of his face . It is the Doctor . He and the resistance fighters are all dressed as World War I soldiers . They dress Jamie up and march through the compound . They disable the guard controlling the computer in the landing bay .

A fight breaks out , and Moore is knocked out . Russell wheels around to see Von Weich armed . He tells Russell they are to go back in the machine and return to the headquarters . Russell refuses . Von Weich says he will kill him . Russell still refuses . A gun shot rings out . Von Weich falls to the ground . Russell turns to see Moore with the shot gun in his hand . The Doctor , Jamie and Carstairs have made it back to the processing room . The War Chief and the Security Chief are still at loggerheads . The Security Chief thinks that the Doctor ' s ability to operate the machinery seems to imply he is a Time Lord . The Doctor has removed the reprocessing unit . As they leave , they find some gas - filled valves . As they make their way into the processing room , the guards attack them . The Doctor throws the valves on the floor , releasing the noxious gas . They make it to the machine and begin to dematerialise . Their joy is short lived as the machine soon stops . The Doctor operates the emergency lock and sets about trying to override the master control . The Security Chief orders the Doctor ' s surrender . The machine is surrounded . The Doctor reassures his friends that the machine is impregnable . The Security Chief intends to wait , but the War Chief has other ideas . He activates the dimensional controls of the machine . Inside , the walls begin drawing in . The War Chief says they have thirty seconds to surrender or they will be crushed . Episode seven . As the machine ' s dimensions contract , the Doctor says they have to do as the War Chief says . The War Chief goes to reduce the dimensions further when the door opens . The Doctor crawls out . The War Chief orders the others to come out too . The Doctor throws one of the gas valves on the ground and , as everyone else is coughing and blinded , covers his mouth and rearranges the controls . He returns to the machine , which dematerialises . Once the gas has cleared , the War Chief realises that the Doctor has locked the remote control .

When the War Chief is alone with the Doctor , he tells him that he recognises him even though he has changed his appearance . The Doctor says that he had every right to leave his home planet . The War Chief questions the morality of stealing a TARDIS and goes on to say that he and the Doctor are very similar , an accusation the Doctor strenuously denies . The War Chief asks the Doctor if he knows the final objective of the war games ; when he replies in the negative , the War Chief tells him that the aim is to whittle the best soldiers from the most aggressive planet into a super army whose objective is to enforce peace to the Galaxy .

Later , some resistance fighters storm a Roman military camp and destroy their communication unit . This registers with the Security Chief , who sends a guard . Carstairs is also informed . He says the Crimean War Zone is next . A soldier in the Crimean War Zone is attacked by resistance fighters , and the communications unit is destroyed with dynamite . Again , this registers with the Security Chief who sends a squad of guards . At the chateau , Russell is informed of the number and location of all guards sent by the Security Chief , and Jamie and Zoe place it on a map . Soon enough the map is peppered with numerous guards . Russell informs them it is now time for phase two : the attack on the barn . They are to leave one by one so as not to arouse suspicion . In the barn , a wounded soldier goes for the telescreen , but Arturo ' s men shoot him just in time . The Security Chief has noticed the pattern , but it is too late . There are few guards left at headquarters and none have returned that he sent out . The War Lord and War Chief are critical of the Security Chief . The Security Chief says that the resistance fighters have to be in the American Civil War Zone as it is the last place yet to be attacked .

The Doctor flatters the War Chief as to the technological advances of his machines . He states that in his day such machines with pinpoint accuracy would be at the expense of a terribly short lifespan . When the Doctor asks how he did that , the War Chief brushes the question off . The Doctor realises that the War Chief hasn ' t fixed the problem and that he needs the Doctor ' s TARDIS to escape . The War Chief says that if they two escape in his TARDIS , they can rule over the galaxy together .

The Security Chief plays back the recordings and orders the arrest of the War Chief . The guards drag him away and the Security Chief orders the Doctor ' s arrest .

Zoe sees the guards coming . The resistance leaders overpower them and liberate the War Chief . The War Chief tells the Doctor they have been discovered , but the guards at the Landing Bay do not know yet , so they should go there and redirect the returning guards .

Zoe questions the Doctor as to what the War Chief was so scared of . The Doctor says he is going to have to contact the Time Lords . When Jamie says that there is no danger from his own people , the Doctor contradicts him , but he has no choice . He sits on the floor and lays out six cards in a circle . He goes into a trance . The War Chief tries to stop him but is restrained . The cards form a cube . The Doctor wakes and explains that the cube consists of all the information about the War Games and a plea for help for the Time Lords . They realise that the War Chief has gone .

The Doctor quickly says goodbye to Carstairs before sprinting to the TARDIS . The travellers turn to look back and see Carstairs disappearing into the mist . As they run they are struck down by the mist . The Doctor crawls towards his TARDIS as the mists consume him . He gets the key in the door before falling unconscious . Episode ten . The Doctor identifies the thing slowing him down as a force field employed by the Time Lords . The Doctor , Jamie and Zoe work as a team and open the door . They crawl in , but the force field is affecting the inside of the TARDIS too . The Doctor suggests that if he dematerialises it might break through the force field . He does so and it proves true . His companions ask him why he is running away from his own people . The Doctor explains that Time Lords have the ability to live forever barring accidents and the power of travel through space and time , but they never use it for good . They just gather knowledge of events . The Time Lord code is to never interfere or help . He has set the TARDIS for a planet on the outermost fringes of the galaxy , but the TARDIS begins landing prematurely . The Doctor rushes to the scanner to see the TARDIS land on the sea . Zoe says that the TARDIS has landed on the sea before and has been fine , but this time the scanner shows that they have continued to go underwater .

The Doctor takes them to the one place where they might be safe . He moves the TARDIS into the middle of outer space , hoping they won ' t be detected . A voice comes from nowhere , saying that there is no escape and that the Doctor needs to return the TARDIS to his home planet immediately . Reluctantly , the Doctor seems to agree before quickly attempting a transference jump somewhere safe . He fleetingly ends up in crocodile - infested waters before they are on the move again . The scanner doesn ' t show anything until it zones in on a corridor . The voice confirms the Doctor has returned to his home planet . Disconsolate the Doctor emerges . They are met by a Time Lord whom Jamie tries to challenge ; the Doctor calls him off . The Time Lord leads the Doctor , Jamie and Zoe into a courtroom where they are ruling on the War Lord . The Time Lord in charge says that all surviving soldiers have been returned to their own time , but many have died and many more would have died if the War Lord ' s plan had been brought to bear . The Time Lords accuse the War Lord of breaking all galactic laws . The Doctor tells Jamie and Zoe that this is a rare thing to see as the Time Lords rarely hold court . Zoe asks if they can escape . The Doctor confides that his companions might , but it is unlikely he will . The Doctor is called as a witness . He states that all the knowledge possessed in the cube is truthful . The Time Lords call on the War Lord to speak , but he refuses . The Time Lord in charge fixes him with a stare that causes a blinding pain in his head . The War Lord begs the noise to stop . The War Lord denies the court the authority to prosecute him and states that the soldiers would have killed themselves anyway . He also says that the Time Lords are complicit with him as both the War Chief and the Doctor were working alongside him . The Doctor denies this . Some Time Lord scientists are observing the TARDIS when they hear the sound of dematerialisation outside . They emerge to see one of the machines . Some guards come out and kill the scientists . The Time Lords have found the War Lord guilty and say that his accusations towards the Doctor are fraud . The guards rush in and seize the Doctor , Jamie and Zoe as hostages . The Time Lords let them go . The War Lord insists the Doctor is to help them and forces them into the TARDIS . Jamie insists that the Doctor has no control over the TARDIS , but the War Lord doesn ' t believe this . He says that the Doctor will make him many TARDISES . He orders the Doctor to take him to his home planet or Zoe will be killed . The Doctor approaches the console and shouts for Jamie and Zoe to cover their eyes . A blinding light cripples the War Lord and his guards , and they run to the Time Lords . A force field is placed around the TARDIS , trapping the War Lord and his guards . The Time Lords say a similar force field has been placed around their home planet to protect the galaxy from their kind . The War Lord and his guards are dematerialised so it was as if they never existed . Jamie thinks this is the end of the ordeal and walks towards the TARDIS , thinking they can all continue their adventures . The Doctor tells him that they will not be allowed to go . The Doctor is led away to his own trial , whilst Zoe and Jamie are trapped inside a force field . The Time Lords accuse the Doctor of breaking their laws of non - interference . The Doctor admits doing so and is proud of it . He is proud of having fought evil and not merely observed it . He asks for a thought channel to show the evil he has fought . He shows the Time Lords the Quark s and the Yeti . They are not impressed . He goes on to show them the Ice Warrior s , the Cybermen and the Dalek s . He ends by saying that he may be guilty of interference , but they are guilty of passivity against such evil . The Time Lords say they need time to think and that the Doctor will be recalled when they have made their decision . Jamie and Zoe are still calling to be freed from their force field . A Time Lord arrives , drops the force field and tells them he is there to return them home . They beg to see the Doctor , and the Time Lord relents . The Doctor is playing cards inside a force field . The Time Lord switches it off to allow Jamie and Zoe in and leaves them to say goodbye . Zoe asks what punishment he is likely to get .

They make their way back to the TARDIS but are intercepted by a group of Time Lords and a force field . The Doctor says there is no escape . He bids goodbye to Jamie and Zoe . They make their way into the machine and it dematerialises . A Time Lord says that they will wipe their memories so they have no knowledge of the Doctor . Later in the court , the Doctor watches Zoe as she returns to the Wheel at the exact moment she left . Everything is fine except she says she feels like she has forgotten something important . He then asks to see Jamie , who wakes up in the middle of nowhere and immediately is shot at by a Redcoat . Jamie attacks him with his sword . The Doctor chuckles and turns to his people . He enquires what fate has in store for him . They have accepted his plea that evil has to be fought and that he has his part to play in that . He asks if he is to go free . The Time Lords says he is to be exiled on the planet Earth in the 20th century — as it is there that he has shown the most affinity . In addition , the secret of the TARDIS is to be taken away from him . The Doctor is appalled by this . He says that he is known on Earth , and it could cause him some difficulties . The Time Lords say they will change his appearance again . He is furious at this but is placated when he is told that he can choose . He is shown five faces that he successively adjudges to be too old , fat , thin , young or that " it won ' t do at all " . He wheels around and begins to shout at the Time Lords but starts to lose function and the ability to talk . He goes into a daze . He is still railing against his punishment as he begins to drift into nothingness . Story notes . Ratings .
