In a daze Tom staggers towards a police box and opens it to discover it is the Doctor ' s " Tardis " . His injuries , combined with the shock of " Tardis " , cause him to faint . The Doctor uses his scanners to see that there is a kerfuffle outside and leaves with Tom on board before any one else makes the same mistake as he did . When Tom awakes he is introduced to the Doctor , Louise and Susan . He is eager to get out and report the crime - the Doctor tells him this is impossible , as the year is 2150 AD . Tom reacts to this news with scepticism and says that he will report the Doctor for wasting police time . He exits " Tardis " to find himself in a barren and deserted area of London . Tom is initially very confused . As the travellers go off to explore Susan accidentally loosens some debris which causes a building to toppled over trapping " Tardis " in rubble . The Doctor and Tom go off to find something to help loosen the debris . As they explore an abandoned warehouse they see a figure in amongst some boxes . They discover it is a dead man dressed in futuristic clothing and wearing a helmet with a receiver in it . Back at " Tardis " Louise returns from getting water to find Susan gone . A man grabs her and tells her that Susan has been taken to safety , and that the two women should never have been out there at all . The man takes Louise with him to meet Susan . The two men go back to join the women but discover them gone . As Louise and her mysterious friend enter an abandoned Tube station , Louise is stopped in her tracks by the sight of a space ship looming over London which the Doctor and Tom also see . In the tube station Susan and Louise are reunited and the man who saved them both reveals himself to be called Wyler . He introduces them to the rest of the underground rebels who are fighting the alien species that are attacking London . A man named David goes out to look for the Doctor and Tom on the advice of a very distressed Susan . Back at " Tardis " , the men are taken siege by the Robomen , who start firing guns at them as they run they are trapped in by the river . Much to their shock , they see a Dalek emerge from the river also . The men are captured and led away to one of the Dalek saucers . Little do they know David has been watching all this and will return home to share the bad news . In the underground hideout Susan and Louise are introduced to the leader of the underground rebels , Dortmun - a disabled weapons expert . As they are introduced they are interrupted by a radio bulletin from the Daleks urging all rebels to surrender themselves or face the wrath of the Dalek . Dortmun reveals to the women that he has constructed a bomb that will bring the Daleks to their knees . He also explains to them how the Daleks took over Earth , through a strategic bout of meteor attacks and segregation . Dortmun expains the strangest act of the Daleks is to start a mining facility in Bedford staffed by human slaves . David returns to the underground network and tells the girls that their friends have been imprisoned and that the saucer is where Robomen are created . Dortmun , David and Wyler discuss how to take the Daleks down . Dortmun suggests dressing as Robomen and getting on to the saucer and then attacking from the inside . As the Doctor and Tom are led to the saucer , the Doctor explains to Tom that he has encountered the Daleks once before at the end of their civilisation but that " Tardis " must have put them down much earlier on in their timeline . His story is interrupted by the a prisoner trying to escape . He is soon exterminated by the Daleks who warn the other prisoners that this will be their fate if they try anything similar . The Doctor and Tom are locked in a cell , but the Doctor soon discovers that the doors are powered through magnetics and uses a comb to break the magnetic attraction . As soon as he is free the Daleks recapture him and say that he has passed the intelligence test and will now be robotised along with Tom . The men are led away . As they are prepared for the transfer , the rebel faction aboard the ship . They are challenged at the top of the ramp , and the Dalek realises the trick . A battle ensues with many casualties on either side However , this enables the Doctor and Tom to escape from the transfer - although they soon get split up in the melee . Tom hides away inside the saucer as does Louise who was part of the rebel faction . The Doctor escapes from the ship with David , and are pursued through London by the Daleks . They hide in a sewer network until the Daleks lose them . The boms provedfutile and while they caused damage to some Daleks did not damage their saucer at all . Tom disguises himself as a Roboman and joins a pack of Robomen in order to remain inconspicuous on the saucer . Eventually , he is reunited with Louise and they hide away on the saucer together . Back at the Underground station , Susan and Dortmun wait patiently for news of the siege . A badly injured Wyler returns to say that most of the men have been wiped out as the bomb was ineffective . When Susan asks about the Doctor he confirms that he saw him escape with David . The trio decide to go to Watford so they can access more weaponry . Susan leaves a message for the Doctor written in chalk on the door of the station . The Doctor and David return to the underground station and find it deserted . Unaware of the note on the door , the Doctor and David look through Dortmun ' s plans and incorrectly assume that he and Susan will have gone to Bedfordshire to examine the mining colony . David and the Doctor decide to join them . As they leave the underground station they see the saucer take off unaware that Tom and Louise are still in there . Dortmun , Wyler and Susan have come across a van which they intend to use to drive to Watford . Dortmun goes out to check if the coast is clear and sees a group of Daleks . On a whim he starts to attack them with his bombs . Frustrated with the futile effect of them he throws the whole bag at them which cause the building he is standing next to collapse and kill him . Wyler panics and starts to drive away . The disturbance has drawn a crowd of patrol Daleks who create a roadblock which Wyler drives through . One of the Daleks reports to the saucer that a patrol has been breeched . the saucer redirects itself and blows up the truck . Luckily , Wyler and Susan have jumped to safety before the explosion . When the saucer comes to land . Louise and Tom use a waste chute to escape into the outside world . they find themselves in the mining colony and start to explore . They are set upon by a Roboman but are saved by a kindly stranger who kills the Roboman he finds a small shed for the couple to stay in until the trouble has died down . Wyler and Susan are now forced to carry on with their journey on foot . They come across an old farm cottage where a woman and her mother live . The woman points a gun at the pair asking where they are going . Susan responds they are going to Bedfordshire - much to the confusion of Wyler . Eventually the family welcome them in . Susan explains to Wyler that she is sure that the Doctor would have seen all the Daleks in Watford and decided to go to Bedfordshire so they may as well go there too . The daughter of the family leaves her Mother to look after the guests as she has errands to do . The mother offers the travellers some soup . The Doctor and David have arrived at Bedfordshire . The Doctor suspects that they are trying to mine the magnetic core out of planet Earth and David says that Dortmun was sure that they were doing so to use the Earth as a massive space ship that they could pilot around the universe . The Doctor concurs that this is his view too . They are interrupted by a man who comes upon them with a gun . He says he is a black maketeer who for a price will smuggle them into the camp . They wait in a cave until night fall to make the move . Back in the cottage Wyler and Susan are asleep . However , when the daughter returns Wyler wakes and hears that the daughter has betrayed them to the Daleks . As they try and escape they come across the Daleks waiting for them outside . They are led away . In the morning , the two men are smuggled into the camp and by chance are led to the same shed where Louise and Tom are hiding out . They are soon joined by a man who is paying for food that the black maketeer has smuggled in . The Doctor sets about using the shed as his HQ . The man informs the Doctor that the final stage of the Dalek ' s place will take effect tonight . They are dropping a bomb to the very centre of the Earth that will ensure that they will be able to implement their on technology at the centre of the Earth and pilot it at their whim . The black maketeer says that he will be able to get a plan of the workings of the mine to help the Doctor take the Daleks down . When the Doctor gets the plans he realises that the bomb could be deflected which would mean that the explosion would trigger the polarities of the magnetic poles and cause a massive magnetic surge pinpointed at the mineshaft . He asks Tom and see if he can deflect the bomb in the shaft at all . He sends the others to hide elsewhere whilst he fine tunes his plans . Soon the black marketeer returns to the Doctor saying that he has something to show him . The Doctor goes outside to find that he has been betrayed and the Daleks surround him . The black marketeer apologises but the Doctor says that his betrayal was part of his plan . As the Doctor is led away the black marketeer is killed anyway . Tom has accessed the mine from the bottom and is slowly climbing to the very top where the Daleks ' control centre lies . As he nears the top the Daleks are preparing the bomb . However , they are interrupted by the Doctor who has been reunited with Susan and Wyler who have also been taken on the ship . The Doctor is led into the main control panel of the theatre as they think him the leader of the rebels . He tells the Daleks that he knows their weakness and simultaneously tells Tom , who he sees down the shaft , at what angle to place the wooden slats he hasfound in order to deflect the bomb in just the right way to trigger the strong magnetic force he desires . To further disrupt the Dalek operation as well as give Tom more time , the Doctor utilises the microphone with which the Daleks control the Robomen and orders them to attack the Daleks . This rebellion is soon crushed by the Daleks and the countdown for the bomb is started . The bomb is launched by which time Tom has created the diversion . the bomb goes off which causes the magnetic surge . The Daleks are all pulled into the mine shaft or crushed against walls or caves . The Daleks try to escape in their saucer but the magnetic force forces the ship to crash . The Doctor informs Wyler that the Daleks will never return to this planet as this was their warning . Back on " Tardis " , Tom asks to be taken back to a few minutes before the robbery took place . He waves goodbye to the Doctor before he goes to the car of the getaway driver and knocks him out and takes his place at the driver ' s seat . When the criminals rush out the building they find a policeman waiting for them who knocks them both out and drives them to the police station anticipating his promotion . TV to film changes . Here are a few of the notable plot changes made between the TV version of the story and the film ( not including the fundamental differences involving the character of Dr . Who himself when compared to the mainstream First Doctor ) : Novelisations . No novelisation of the screenplay was ever published ; however , the original teleplay , " The Dalek Invasion of Earth " , was eventually novelised by Terrance Dicks in 1977 as " Doctor Who and the Dalek Invasion of Earth " .
