The Enemy of the World ( TV story ) The Enemy of the World was the fourth story of season 5 of " Doctor Who " . It saw Patrick Troughton play both the lead protagonist and antagonist . It was the only story of that season which did not follow the " base under siege " monster format . Before 2013 , all but episode three of the serial were missing from the BBC archives . However , in October of that year , it was announced that episodes one , two , four , five and six ( together with four previously lost instalments and a higher quality copy of the only existing episode from " The Web of Fear " ) had been located in a relay station in Jos , Nigeria , and it therefore became complete . It was released on DVD in Region 2 on 25 November 2013 . Synopsis . On Earth in 2018 , the Doctor and his companions are enmeshed in a deadly web of intrigue thanks to his uncanny resemblance to the scientist / politician Salamander . He is hailed as the " shopkeeper of the world " for his efforts to relieve global famine , but why do his rivals keep disappearing ? How can he predict so many natural disasters ? The Doctor must expose Salamander ' s schemes before he takes over the world . Plot . Episode 1 . The TARDIS arrives on an Australia n beach , Cape Arid , where the Doctor , Jamie and Victoria ' s seaside frolicking is observed by three men in a hovercraft named Anton , Curly and Rod . They are incredulous at the Doctor ' s presence ; could it be " him ? " They call their boss , Astrid Ferrier , who disbelieves their story and urges them to wait while she contacts the main base . Nonetheless , their leader , Anton , resolves that they ' ll have no better opportunity , and they ready their guns . Astrid contacts her commander , Giles Kent , and reports the men ' s observation . It can ' t be him , Kent exclaims , it ' s impossible . He orders her to stop the men from harming the Doctor . The Doctor , Jamie and Victoria watch as the hovercraft approaches , see the armed men and realise they ' re in danger . They begin to run as Anton and Rod shoot at them from the hovercraft . They hide behind some dunes , and the men are forced to split up in order to find them . The Doctor and his colleagues try to escape but soon run into one of the men . Jamie knocks him out . The men see the approach of a mini - helicopter and identify it as Astrid ' s . In their efforts to elude the gunmen , the Doctor and his colleagues end up in the same clearing in which Astrid landed her helicopter . She beckons them inside . Once inside , the Doctor sees Astrid ' s pilot ' s licence and sees it is valid until the end of 2018 . Astrid informs them that the men have punctured the fuel tank and that the helicopter could explode at any minute . Below , the men board their hovercraft and pursue the helicopter . Astrid lands her helicopter at her private residence . She has been shot , and the Doctor tends her wounds . She explains her men have mistaken him for their sworn enemy , Salamander , a man she claims is bent on becoming global dictator . She wants to take advantage of the Doctor ' s apparently serendipitous arrival and urges them to go with her to meet Giles Kent , who will explain everything . The Doctor , dubious at becoming a pawn in some political machination , declines . The three armed men close in . Astrid encourages the Doctor and his colleagues to hide in a back room as she hides behind the sofa . Astrid tangles with Curly to allow the Doctor , Jamie and Victoria to escape . Curly is accidentally shot dead by his fellows as they try to kill Astrid . Rod and Anton shoot at the fleeing bunch but realise they stand a better chance in the helicopter . As soon as the helicopter is airborne it explodes . At his office , Giles Kent looks at the Doctor in fascination — his resemblance to Salamander is uncanny . The Doctor explains they ' ve been out of touch with world events lately ( " On ice , " he says , referring to their previous adventures in Tibet and in Earth ' s icy future ) . Kent plays a video - wire of Salamander ' s latest address to the United Zone General Assembly meeting . Salamander , despite a Mexican accent and swarthy complexion , is indeed a doppelganger for the Doctor . He announces highly satisfactory results from sun conservation tests in the Australasian Zone with sun - catching orbital satellites , resulting in a restoration of the Canada and Ukraine ' s corn and flour production which had been devastated by natural disasters two years earlier . The Doctor is confused as to why they are intent on stopping Salamander when his intentions appear to be so good . Kent explains that underneath his guise as a public benefactor , he has been ruthlessly solidifying his power base . Several high - ranking political figures have died under mysterious circumstances and replaced by Salamander loyalists . Kent himself was Deputy Security Leader for North Africa and Europe before being sacked for beginning to suspect too much . Kent was forced into seclusion , and his place was taken by a man named Donald Bruce who has since risen to World Security Chief . With Bruce in place , Salamander is virtually untouchable . Kent ' s only remaining high - ranking ally is Alexander Denes , Controller of the Central Europe Zone . Kent urges the Doctor to pose as Salamander and infiltrate his research station at Kanowa to find proof of Salamander ' s ambitions . The Doctor is dubious but attempts the accent , with limited success . Kent receives a phone call stating that Bruce has cordoned off the area and is approaching . Kent warns the Doctor that if he is found he will be killed due to his similarity to Salamander . The Doctor correctly surmises that Kent tipped Bruce off to test the similarity . The Doctor is given no choice but to imitate the dictator . Astrid shouts at Kent for endangering them . Bruce enters , a heavy - set , imperious and intimidating man . His armed men are investigating the dead man in Astrid ' s house , as well as the wrecked helicopter . He explains that Astrid was being watched and that a man was present . Astrid refuses to explain who the man was , and Bruce motions to his guards to search the building . As they open the door to the back room , " Salamander " emerges , demanding that a dumbfounded Kent explain his presence . Episode 2 . Bruce is dumbfounded by Salamander ' s presence in Australia , when he is supposed to be in a closed - door conference at the Central European Zone , and certainly not with Kent , a man he had denounced . As security chief , he ought to have been told . " Salamander " refuses to explain his presence , saying he will deal with Kent his own way . Bruce is sceptical of Kent ' s explanation that the dead man in Astrid ' s house was trying to protect her from his treasonous colleagues , but " Salamander " overrules him and dismisses him . Giles congratulates the Doctor and assumes he is fully on board now , but the Doctor still is not fully convinced that one side or the other is good or evil . He asks his companions ; Jamie says they have to help , but Victoria is unsure . The Doctor agrees to pose as Salamander at the Kanowa Research Centre . Astrid , Jamie and Victoria , using travel passes provided by Denes , the leader of the Central European Zone , are to travel to Salamander ' s headquarters in the Central European Zone via rocket and put into place a plan that Astrid has been forming for some time . Bruce checks in with Benik , Salamander ' s deputy , to confirm he left for the Central European Zone . As far as Benik knows , he did and left strict orders not to be disturbed . His attempt to contact Salamander there goes unanswered . Bruce informs him that he thinks Salamander is in Australia ; Bennick is dubious . The real Salamander is meeting with Denes and another man by the name of Fedorin and is trying to persuade them that his scientific study confirms that a range of dormant Hungarian volcano es will erupt soon with cataclysmic results . Denes is dubious at Salamander ' s suspiciously precise predictions ; his own scientists have made no such forecasts . This act of defiance annoys Salamander . Denes leaves , but Salamander asks Fedorin to stay . Jamie , Victoria and Astrid have arrived in the Central European Zone , and Astrid has set Jamie up with ID to get past the main guards . Jamie heads off . Astrid contacts Giles in Australia and tells him that all is going to plan . She also explains that she is to meet Denes later . Fedorin is nervous about his meeting with Salamander . He gets chatting to a servant of Salamander ' s named Fariah . Salamander appears and orders a guard who approaches Fedorin , gun raised . As he does , Jamie leaps from an unseen point , knocks the guard out and points the gun at Salamander , ordering them all to back up . Jamie grabs Salamander ' s security device and throws it over the balcony . As he does , Astrid triggers an explosion outside . Two guards enter and approach Jamie , but Salamander calls them off . Jamie explains that there was a plot on Salamander ' s life and that he tried to inform the guards on the gate , but they wouldn ' t listen . Impressed , Salamander offers Jamie a job . Jamie says he would like to but is only visiting with his girlfriend and wouldn ' t want to leave her . Fariah says there is a job working in the kitchen . Jamie agrees and is allowed to go and get his " girlfriend " . Fedorin mysteriously asks what the word " brujo " ( a word uttered by Fariah ) means . Salamander says it is the word for " sorcerer " which is used in Mexico . Jamie returns to the meeting spot and tells Victoria and Astrid that the plan has worked . Astrid disappears as Fariah comes to collect Jamie and Victoria and take them into the base . Later that day , Denes meets Astrid under a jetty . Astrid wants Denes to stall Salamander while she puts her plan in place . They hear feet above them . Denes stops Astrid from shooting them on sight . Salamander shows Fedorin an official file of lies , scandal and libel he has concocted about him . Fedorin is very worried , but Salamander refers to it as insurance . Salamander offers Fedorin the job as leader of the Central European Zone if he promises to share the power with Salamander . Fedorin asks what is to happen to Denes , and Salamander explains he is to be killed . Fedorin says he can ' t do that , but Salamander reminds him of the file . The conversation is interrupted by the eruption of the volcanoes . Salamander is overjoyed at the fact that his predictions have come true , despite the widespread destruction he is witnessing below . Bruce enters , worried about reports he heard of an attempt on Salamander ' s life . Salamander placates him . Denes bursts in , horrified at the destruction . Salamander accuses him of ignoring his warnings and letting thousands die . Denes is certain that somehow Salamander engineered this disaster . Salamander coolly denounces Denes as a traitor and orders Bruce to arrest him . Denes implores Fedorin to back him up , but Salamander states that Fedorin will be chief witness against him . All eyes turn to Fedorin . Fedorin cannot even bring himself to look at Denes . Episode 3 . Denes is unperturbed at his arrest . He looks forward to facing Salamander in open trial . After Denes is led away , Salamander congratulates Fedorin on his " promotion " to European Controller and puts his dossier of blackmail documents into a safe . He gives Fedorin a vial of poison to deal with Denes . Bruce is surprised to encounter Jamie , now in Salamander ' s personal guard . Jamie refuses to divulge any details of what Salamander was doing in Australia with his supposed enemy Kent . Victoria meanwhile thoroughly fails to impress Griffin , Salamander ' s chief cook , with her culinary skills . Fariah , Salamander ' s assistant and food taster , urges her to escape at the earliest opportunity . In Kent ' s caravan near the Kanowa research station , he and the Doctor watch footage of the European volcanoes . Kent strongly suspects that Salamander is somehow engineering these disasters , and it was his investigation into how the research station was involved which led to his downfall . The Doctor hides when Benik arrives at the trailer to taunt Kent and smash his possessions . Astrid , Jamie and Victoria try to rescue Denes with Fariah ' s help . Fedorin intercepts Victoria as she delivers his food . He cannot , however , bring himself to poison the food . He confesses his failure to Salamander , who offers comforting words and a glass of wine to help him relax . Fedorin drinks and slumps over dead ; Salamander had poured the poison into the wine . The rescue attempt is a failure : although Astrid escapes , Denes is shot down , and Jamie and Victoria are captured . The light dawns on Bruce when Salamander denies being in Australia with Kent earlier . Someone is impersonating Salamander . . . Episode 4 . Giles is waiting for contact from Astrid and is panicked by the lack of contact . She eventually contacts him , and Giles tells her to scramble her messages to ensure that no one is listening in . Benik is , indeed , listening in and frustrated by the scrambling . He sends his guards out to trace Astrid . He is informed that Salamander is returning to Australia . Astrid explains she has returned to Australia safely and is back at Giles ' office . She explains that Denes has been killed . She is interrupted by a figure at the door . It is Fariah . Astrid is sceptical , thinking she has been sent by Salamander , but Fariah claims she hates him and wants him dead . The guards report to Benik that Astrid and Fariah have been seen together . Benik orders Giles ' office surrounded . The Doctor and Giles have joined Astrid and Fariah . The Doctor is concerned about Jamie and Victoria but Fariah says they have been brought back to Australia by Salamander . The Doctor mistrusts Fariah but she says she has spent her whole life being controlled and blackmailed by Salamander . The Doctor asks if she has any proof . She says she has nothing to prove that she has been blackmailed but has the information he was using to blackmail Fedorin . Meanwhile , downstairs Benik has surrounded the place . Kent and the Doctor look over the evidence , but the Doctor claims it ' s not enough to prove Salamander is evil . However , with Jamie and Victoria prisoners , the Doctor ' s impersonation of Salamander is their only hope . Giles says that when he gets close to Salamander the Doctor must kill him . The Doctor objects to this , but Giles says he will withdraw support in finding Jamie and Victoria . Fariah ' s presence , they hope , will help convince people of his identity . Fariah notices that the place has been surrounded . Benik orders his men to shoot any of the party on sight . The Doctor and his friends soon realise there is no escape other than the ventilation shaft . Benik is at the door . Astrid orders them all to go down the shaft whist she stalls Benik and his men . One of the guards enters through the window . He and Astrid grapple and , on the sound of a gunshot , Benik enters . The only person there is the prostrate guard . He assumes they have all gone down through the ventilation shaft and rushes out to the street . Astrid has been hiding under a desk the whole time . As Fariah tries to escape , she is shot by one of the guards . Benik tries to extract information from her but she refuses . She dies . Benik regains Salamander ' s file from her . Salamander and Bruce lose their mind at Benik for his heavy handed way of dealing with the situation . Salamander is more concerned by his lookalike . Benik returns the file to Salamander . Left alone , Salamander locks himself inside the Records Room . Once he ' s sure he ' s alone , he opens a secret panel in the wall , revealing a small elevator capsule into which he climbs and descends . Bruce tries to contact Salamander . When he discovers he can ' t , he is infuriated at the way that Salamander is running things . Salamander has descended to a vast underground complex . He explains over tannoy that he has returned . A couple , Colin and Mary , discuss how Colin is going to demand from Salamander that he return to the surface . He goes to meet Salamander , who explains that the radiation on the surface is killing him but he has found a store of food . He has convinced them a nuclear war has devastated the surface , and their efforts to create natural disasters are helping them turn the tide against , in Salamander ' s words , " the enemies of truth and freedom " . The research team have been down there for five years . They cannot return until the radiation levels on the surface fall to safe levels . They hail Salamander as their hero , risking life and limb to bring them food . Colin is the lone dissenter , demanding to return to the surface . Salamander feigns radiation sickness and leaves . Back at the caravan , Kent and Astrid prepare the Doctor to infiltrate the station while awaiting the return of Fariah . The door opens and a figure emerges . Episode 5 . The figure is Bruce , who placed a tracking device on the caravan . Bruce demands to know why the Doctor is posing as Salamander . The Doctor says it is to get Jamie and Victoria back , whilst Astrid says it is to expose Salamander for what he is . Bruce says the only bad things connected to Salamander can be laid at the door of Giles . The Doctor explains they have a file , in the hands of Fariah , that proves Salamander is evil . Bruce says that Fariah is dead . Astrid wants to go and intercept the file , but Bruce refuses to let her leave . He is , however , slightly won over and says he will investigate himself . Giles says that someone so close to Salamander is only digging his own grave by doing so . Astrid overpowers and disarms Bruce ' s guard , pointing the gun at Bruce . Benik tells the guard he wants to be informed when Salamander returns . He watches the unloading of a drugged Jamie and Victoria and wants to question them as soon as they are awake . Astrid demands to be taken to the Research Centre , but Bruce calmly notes there are a dozen guards outside . The Doctor defuses the situation and says if there is bloodshed he will not help them in their plans . The Doctor takes the gun off Astrid and hands it back to Bruce as a sign of good faith . Bruce asks the Doctor if he thinks Salamander is evil , and the Doctor says there is enough evidence to suggest it . Bruce agrees to escort the Doctor into the station , provided Kent and Astrid stay behind . They leave , leaving the caravan heavily guarded . In the underground complex , Salamander unloads the supplies from the surface . Colin angrily confronted the leader , Swann , as to why no one can go to the surface and what they would do if Salamander never returned . Swann dismisses him . As he inspects the food packages he finds a scrap of newspaper inside a crate bearing the headline " HOLIDAY LINER SINKS : MANY FEARED LOST " . This appears to indicate that surface life is normal , and Swann angrily demands an explanation . Salamander claims that yes , the war is over , but the survivors are deformed in mind and body and deserve to die . When Swann asks about the creation of the natural disasters , Salamander states that their efforts are to destroy these mutants and this is necessary for a new start . Swann loses his mind at the fact he is complicit in murder . Swann insists on seeing for himself . Eventually Salamander agrees to take him to the surface as long as he tells no one what he sees . Swann informs the rest of the colony . Colin is distraught at the thought of not going . Jamie and Victoria awake and are soon met by Benik . Jamie refuses to tell him anything . Benik anticipates sadistically interrogating them . Jamie disarms a guard , but Benik holds a gun to Victoria ' s head , forcing him to disarm . Jamie is on the verge of caving as Benik begins to harm Victoria , when Salamander enters with Bruce and orders him out . Victoria and Jamie confront Salamander with his crimes , particularly the murder of Fedorin and Denes , which appals Bruce . Victoria lashes out at Salamander , who reveals he ' s actually the Doctor , come to rescue them . He has been maintaining the act to prove to Bruce how good he is . Jamie and Victoria are still unsure until the Doctor mimes his recorder . Bruce is still not convinced to turn against Salamander , but enough doubt is planted that he agrees to investigate . Benik berates a guard for not telling him that Salamander had returned . The guard states that he hasn ' t . Swann follows Salamander through a cave system where he stores the food . Swann questions why he has never brought people up here . Salamander argues that whilst it ' s not radioactive it is too close to the mutants . Salamander warns Swann from going on , but Swann insists . As Swann leads the way , Salamander picks up a metal pole . Kent is furious with himself for allowing the Doctor to go with Bruce alone . Kent will not be calmed and wants to be able to sneak into the Research Centre . Astrid comes up with a plan . She makes it look like Kent has received a bullet to the head and breaks a window to alert the guard . When the guard rushes in to inspect Kent , Astrid sneaks out . As the guard hurries after her , Giles too sneaks out . Astrid has hidden in the undergrowth to evade the guard . As she makes her way through the forest , she hears the cries of a man in distress . She soon finds a severely injured Swann . When she asks who did this to him , he replies , " A man named Salamander . " Episode 6 . Swann tells Astrid that Salamander is in the cave system . The Doctor , Jamie and Victoria try to convince Bruce of Salamander ' s plans . They turn and see Benik , not knowing how long he heard the Doctor using his real voice or about what they were talking . Astrid takes Swann into the cave system to get him some water . He asks her how bad the war was ; when she says there has been no war he tells her about the underground colony and Salamander ' s part in it , then dies . Benik asks the Doctor to sign some papers and also says the door to the Records Room is jammed and asks for his key . The Doctor stalls the signing of the paper and says he has lost his key , then dismisses Benik . When alone , the Doctor asks Bruce how many people work at the Research Centre . The answer is twelve ; but why do they cater for thirty ? His suspicions riled , Bruce tells Jamie and Victoria to leave and phone a man named Forester , who is his deputy , and give him a password to inform him there is trouble . The Doctor tells them to go straight to the TARDIS after doing this . Astrid reaches the band of scientists . The colony workers are shocked and begin to hit and beat her , fearing she is one of the mutant humans of which Salamander has warned them . Colin stops them . Astrid tells them of Swann ' s death at the hands of Salamander and informs them that there is no war . Colin insists she undergoes decontamination . She is taken to the decontamination booth , which reads that she is radioactive but is soon neutralised . Astrid proves this machine is a fake by putting in a ruler which registers as radioactive and then is neutralised . A hubbub breaks out . Astrid tells Colin and Mary they should come with her to the surface . The guards stop Jamie and Victoria from leaving , but Bruce intervenes . One of the guards finds this very suspicious and goes to Benik . Giles has made his way to the Research Centre and overhears a conversation between the guard and Benik , suspicious about Salamander . With his knowledge of the Research Centre , Giles lets himself into the Records Room and finds Salamander . He locks the door before pulling a gun on him . All of this is watched by Bruce and Benik , who attempt to break the door down . Hearing this intrusion , Giles opens up a secret hatch about which he has not forgotten that has enough weaponry to blow the Research Centre sky high . At this point the Doctor drops his act and reveals it has been him all along . He tells Giles he has suspected him for a long while now . As Giles turns to run down the hatch , he is met by Astrid pointing a gun at him . She is accompanied by Colin and Mary , who say that it was Giles who took them down into the colony first , saying it was an endurance test before Salamander took over . Giles points a gun at the Doctor ' s head and explains that it was his plan to kill Salamander and take over , and he still can if he disposes of the evidence . He runs down the hatch . Outside Benik panics and steals a guard ' s gun and tries to run . He is met by Forester and a group of guards . Bruce arrests him . The Doctor contacts Bruce and says that he suspects Giles is about to blow up the Research Centre and that if he can ' t open the door then he should escape . Bruce assures the Doctor they are trying to get in . In the cave system , Salamander jumps out on Giles and disarms him . Giles insists that they can work together once more , but Salamander is unconvinced . He shoots him , only wounding him . Salamander pursues Giles through the cave system . He corners him . Before he has a chance to shoot him again , Giles pulls a lever which triggers a huge explosion . The guards enter the Records Room as the explosion rocks through the centre . Astrid is worried about the people of the colony and risks her life to check they are OK on the TV screen in the Records Room . They are fine , and Bruce assigns her some of his guards to save them . Jamie and Victoria wait nervously near the TARDIS . When the Doctor finally arrives , still disguised as Salamander and clearly wounded and dazed , his behaviour is puzzling ; he orders Jamie to pilot the TARDIS for him — something which neither he nor Victoria were ever allowed to do . When Jamie questions this , the real Doctor stands at the doorway of the TARDIS , mocking Salamander ' s impersonation of him . A desperate Salamander grabs the controls , trying to remember the button Jamie had started to touch , but the Doctor pulls him off the console . A brief scuffle ensues , in which both the Doctor and Jamie are dispatched to the floor by the dictator , who then finds and hurriedly presses the dematerialisation switch . But Salamander does this while the doors are still open , creating a vacuum that blows him out into the space - time vortex while the Doctor , Jamie and Victoria hang on for dear life . . .
