The
Ninth Doctor and
Rose are drawn by a distress signal to a massive bunker beneath Utah in 2012, filled with alien artefacts collected by the bunker's owner, Henry Van Statten. Rose is offered a tour of the facility by
Adam Mitchell, a man who buys and catalogues artefacts for van Statten. Van Statten takes the Doctor to show him a living alien being that he has in captivity, which the Doctor recognises as a
Dalek, a race thought to have been wiped out in the
Time War. The Dalek is seriously wounded and weakened, and unable to break its bonds, but when the Doctor attempts to destroy it, van Statten orders his guards to restrain the Doctor and return him to his offices. There, van Statten has the Doctor secured, noting that not only does he collect aliens, but also tortures them to gain information, and proceeds to invasively and violently study the Doctor's body to learn more about his physiology. Meanwhile, Adam has taken Rose to the Dalek. Rose takes pity on the weakened creature and touches its casing; the Dalek promptly absorbs her DNA extrapolating the biomass of a time traveller, and is able to re-energise itself. It escapes its bonds, kills several guards, and repairs its casing. Connecting to the Internet, the Dalek realises that it is the last surviving Dalek. With no other purpose, it returns to the Daleks' prime directive: to target and exterminate all non-Dalek life forms. Van Statten is forced to release the Doctor to help stop the Dalek, but the Dalek refuses to cooperate, and continues killing all those left in the Vault. The Dalek prepares to kill Rose but is unable to, realising in horror that it can now feel fear after absorbing Rose's DNA, and begins to question itself. The Doctor arrives and prepares to kill the Dalek, but Rose stops him, convincing him he is becoming like a Dalek. The Dalek is unable to cope with its new emotions, concluding that its existence is "sickness". It asks Rose to allow it to die. Rose gives the order, and the Dalek self-destructs. Van Statten's assistant Goddard takes over the bunker, planning to wipe van Statten's memories and fill the bunker with cement. Rose offers Adam the chance to travel with her and the Doctor, since he will have no job after this. Adam accepts the offer. == Production ==
