Bad Wolf ( TV story ) Bad Wolf was the twelfth episode of the first series of BBC Wales " Doctor Who " and the first of the two - part finale . It featured a much larger Dalek presence than earlier in the series . It also re - introduced some Dalek concepts from the original run of " Doctor Who " , including Daleks made from human genetic material and a Dalek Emperor . Narratively , this story marked the impending culmination of the Bad Wolf story arc . Until now , the Doctor had dismissed the cropping up of the phrase Bad Wolf across his travels , but was finally forced to acknowledge it as the precursor to a serious threat upon the universe when it unavoidably stared him directly in the face . Worth noting here were the references made to human pop culture television entertainment at the time of this episode ' s airing , such as " Big Brother " , " The Weakest Link " , and " What Not to Wear " , all given future adaptations far into human history with robotic stand - ins for the original hosts . Several guest voices were provided by their real world celebrity counterparts , Davina McCall , Anne Robinson , Trinny Woodall and Susannah Constantine . Through careful subtext , this was the very first episode to mention the Torchwood Institute as a seemingly forgettable piece of trivia . Inconsequential for the moment , the word " Torchwood " took on greater meaning in the following series when the origins of the Institute were explored . This story also explored how the Ninth Doctor ' s apparently good deeds in " The Long Game " had actually resulted in a decline in the development of the human race . Like " The Ark " some forty years before , " Bad Wolf " was a rare instance of televised " Doctor Who " showing the long - term consequences of the Doctor ' s interference . Synopsis . Separated and with no TARDIS , the Ninth Doctor , Rose , and Jack have to fight for their lives on board the Game Station , but a far more dangerous threat is lurking , just out of sight . The Doctor realises that the entire human race has been blinded to the threat on its doorstep , and Armageddon is fast approaching . Plot . The Ninth Doctor wakes up , curled into a foetal position on the floor of a cupboard . He stumbles out in a daze , and is informed by a young woman , Lynda Moss , that his disorientation is due to the effects of the transmat . Lynda states that he has been chosen as the newest housemate . The Doctor looks around , noticing the cameras , and then a computerised voice requests that he report to the Diary Room . To his disbelief , he is in the " Big Brother " House , live on Channel 44000 . The voice reminds him not to swear . Astounded and annoyed , the Doctor replies , " You have " got " to be kidding . " Rose awakens on the floor of a darkened studio , also disorientated by the transmat that brought her there . A man , Rodrick , tells her to remember to do exactly what the android says . Rose asks what android , but a floor manager calls for people to take their positions behind very familiar looking podiums , one of which has her name on it . As the round - headed android is activated , Rose realises that it is the " Anne Droid " ; she is playing " The Weakest Link " . Jack wakes up and finds himself faced with two gynoid s , Trine - E and Zu - Zana , who offer to give him a brand new image , à la " What Not to Wear " . The two gynoids criticise Jack ' s clothing and comment that his style is very 20th century . A " defabricator " strips him naked in preparation for a fashion makeover ; Jack seems to rather enjoy the idea of being nude in front of millions of viewers and comments that the viewing figures just went up a result . Meanwhile , the Doctor tries , unsuccessfully , to find a way out of the House using the sonic screwdriver . Lynda asks , nervously , if people on the outside watching like her and the Doctor lies , reassuring her that people think she is sweet , which seems to please her . The amnesia caused by the transmat starts to clear , and the Doctor remembers . The TARDIS had left Raxacoricofallapatorius and then visited Kyoto , Japan in 1336 . They had just escaped from that , and were laughing in the TARDIS control room when a bright light , the transmat beam , came through the walls and enveloped them . The Doctor tells Lynda that no ordinary transmat beam could have penetrated the TARDIS , which means this is not just a game ; there is something else going on . He tells the camera that he is going to get out , find his friends , then find whoever is responsible . Two programmers , a man and a woman , who are watching the games from a control room elsewhere , are puzzled at the appearance of the three new contestants , as if the games are running themselves . When eviction time comes around in " Big Brother " , housemate Crosbie is voted out , and she exits the House into a white corridor . At first , the Doctor is puzzled at everyone ' s emotional reaction , but is horrified when he sees Crosbie disintegrated . The Doctor asks the others if getting on television is worth the risk of dying , but Lynda and Strood tell him they have no choice . The contestants in this era are chosen at random from the Earth ' s population and transmatted up to any of 60 " Big Brother " Houses playing simultaneously : winning simply means they get to live . The Doctor realises that Rose was also caught in the transmat and is probably a contestant . To get out , he uses his sonic screwdriver to deliberately destroy the House camera in order to be selected for eviction . In the makeover room , a naked Jack is quite enjoying his experience of having a makeover , but is now faced with the two androids who decide that , quite apart from the fashion makeover , that he should have a face - off — literally . With various cutting instruments , including a chainsaw , the two androids are about to perform some gruesome surgery . They suggest that Jack would look good with a dog ' s head . But to the astonishment of Trine - E and Zu - Zana , Jack pulls out a compact laser deluxe pistol from an intimate hiding place behind him and promptly blows their heads off . Soon the first round of " The Weakest Link " has been and gone and Rose , not being a native of the 2001st century , knows almost none of the answers to the questions pertaining to this time . She is more amused than upset at the situation , until she discovers that being declared the weakest link at the end of each round does not just result in expulsion , but disintegration by the Anne Droid . The contestants continue to be whittled down ( one contestant quits and attempts to flee but is disintegrated ) , with Rodrick voting out everyone except Rose so that when it comes to the final round , he will win by answering questions that Rose cannot answer . He will then collect his prize , in the form of credits , courtesy of the Badwolf Corporation who run the Game Station . At the mention of the name , Rose recalls how the phrase " Bad Wolf " has been following them — from Gwyneth seeing it in her mind in 1869 Cardiff ; the call sign of Henry van Statten ' s helicopter ; the " Blaidd Drwg " nuclear power plant ; as graffiti on the side of the TARDIS in 2006 ; and a news channel on Satellite 5 in the 2001st century . She realises that if the Bad Wolf is in charge , then her presence has been planned . In the House , the Doctor cheerfully walks into the white corridor and waits as the countdown towards eviction ticks towards zero . However , nothing happens — the Doctor has guessed , correctly , that whoever brought him wants him alive . He uses the sonic screwdriver to open the exit to the House , and offers to take the surviving housemates with him . Strood refuses , but Lynda , after some hesitation , follows . The House is just one room of several opening onto a larger chamber , which the Doctor recognises as that of Satellite 5 , but a century later than when he was last there . The Doctor begins scanning the other doors , looking for an exit and asking where his friends could be . Lynda says they could have been transported into any of a hundred different games , all deadly . When the Doctor tells Lynda that he is a traveller , she asks if she could go with him . He smiles and agrees it would not be a bad idea , but right now , they have to concentrate on getting out and finding out who controls the satellite . When Lynda turns the lights on to reveal the logo of the Badwolf Corporation , the sight of it gives the Doctor pause . In the control room , the two programmers decide to look at the transmat logs to see how the travellers got on board . However , the female programmer is refused entry to Archive Six , where the logs are kept . The Controller , a pale woman hooked up by dozens of cables to the station , tells her it is out of bounds . The Controller is constantly monitoring the transmissions that flow through her and muttering almost agitatedly to herself . The male programmer tells her about the new contestants wandering around outside the games and asks for security measures , but she denies them , insisting that the travellers are " no one " and telling them to return to work and alerting them to an impending solar flare . Jack has converted the defabricator beam into a ray gun , and he goes in search of the Doctor , finding him by scanning for the Time Lord ' s bicardial circulatory system . On an observation deck , Lynda fills the Doctor in on what has happened to Earth since his last visit . To the Doctor ' s horror , instead of human development having got back on track , things have in fact become worse . When the Doctor shut down Satellite 5 , all information broadcasts ceased , the whole planet froze , and society collapsed . Human s are still a race of mindless sheep , endlessly watching the programming that the Game Station transmits . Jack finds them as the Doctor frantically tries to access the computer system to find Rose . The Doctor explains that the station is transmitting more than just games , and that whatever the Bad Wolf is , it is manipulating him , creating a trap that Rose is still inside . On Floor 407 , the final round in " The Weakest Link " does not go well for Rose . She loses the round to Rodrick just as the Doctor , Jack and Lynda burst into the studio . When Rose runs towards the Doctor to warn him about the Anne Droid , it shoots Rose , turning her into a pile of dust . Numb with shock , the Doctor does not put up resistance when the guards arrive and take all of them away , despite Jack threatening Roderick and the floor manager . The Doctor remains silent when the guards process and interrogate the three of them , but when they are about to be transported to a lunar penal colony , the Doctor gives the word . He and Jack spring into action , knocking out the guards , grabbing weapons and heading up to Floor 500 . In the control room , Jack and the Doctor wave the weapons at the programmers , ushering them to one side . The Doctor demands to know from the Controller who is in charge and was responsible for killing Rose , but the Controller does not answer . The male programmer is nervous because of the large gun the Doctor is carrying , but the Doctor casually tosses him the weapon , saying he was never really going to use it . The male programmer explains that as the Doctor is not one of the staff , the Controller ' s systems do not recognise him . The Controller was installed when she was five years old ; she has been plugged in so long that her eyes have atrophied from disuse — all she sees is the programming . The male programmer also says that there is more going on at the station ; unauthorised transmats and encrypted signals have been going on for years . Jack opens Archive Six , and finds the TARDIS inside . He goes into it and activates the console , discovering something that shocks him . The predicted solar flare happens , and static floods the screens , blocking transmissions . The Controller unexpectedly calls for the Doctor , explaining that while the solar flare is happening , her " masters " cannot read her thoughts . They have been controlling her mind all her life , but she saw the Doctor in the transmissions and brought him here , hiding him inside the games so he could find her . However , she cannot tell the Doctor who her masters are , because she has been genetically altered to be unable to say their name . Her masters have been hiding and shaping the Earth for centuries , growing stronger in numbers , but they fear the Doctor . As the flare passes , Jack returns and tells the Doctor that the TARDIS worked out that the disintegrators were actually part of a secondary transmat system — people have not died , they have just been transported elsewhere , which means Rose is still alive . Rose regains consciousness aboard an alien spacecraft , where a strange humming sound fills the background . She sees one of the inhabitants of the spacecraft approaching her , and she backs up against a wall in shock as she recognises it , and cannot believe her eyes — she claims to have seen the creature , who presses its plunger - like hand to the wall , die . Back on the station , the Controller gives the Doctor the co - ordinates to where Rose had been transported , despite knowing that she will be revealing her subterfuge to her masters . As she shouts out the co - ordinates , the Controller is teleported away . Materialising on the same ship that Rose has been transported to , the Controller gloatingly tells her masters that they can kill her now , as she has brought about their destruction . She is promptly killed by an energy weapon . On the station , the transmat beam is traced to a point at the edge of the solar system . Although the screen appears to show empty space , there is another signal , transmitted by the satellite , that is shielding what is actually there from detection . These are the same people who installed the Jagrafess nearly two centuries before and have been manipulating mankind for generations , playing a long game . The Doctor cancels the shielding signal and is greeted with an impossible sight — a fleet of two hundred Dalek flying saucer s each containing more than two thousand Daleks , a force almost half a million strong . Both the Doctor and Jack thought the Daleks had all been destroyed , but obviously they somehow survived . The Daleks open communications , with a lead Dalek ordering the Doctor not to intervene with the Dalek stratagem or they will exterminate Rose . To the Daleks ' surprise , the Doctor simply says no . When the lead Dalek demands an explanation , the Doctor defiantly tells them that he is going to rescue Rose from the middle of the Dalek fleet , save the Earth and then wipe every last Dalek out of the sky . The lead Dalek retorts that the Doctor has no weapons , defences or plan . The Doctor taunts them and knows that is exactly what is scaring the Daleks to death . The Doctor tells Rose he is on his way , and cuts the transmission . The lead Dalek states the Doctor has initiated hostile actions , and the Dalek on the left orders the invasion of Earth to begin . Many more Daleks gather for the invasion , all chanting their battle cry : " Exterminate , exterminate , exterminate . . . " Story notes . Filming locations . " to be added "
