The Doctor (David Tennant) runs into some new, and old, acquaintances on a trip back to Victorian London. Arriving to investigate a series of mysterious deaths, the Tardis touches down in a London under the grip of fear. Things soon take a strange twist when the Doctor realises he's not the only Doctor in town, and with events getting out of control, it's not long before the time lords are forced to join forces to combat their common foe. But things are about to get a lot worse for the Doctors, as some of their deadliest foes, the Cybermen, re-emerge to do battle with their old enemy. The programme also includes 'Doctor Who at the Proms', hosted by Freema Agyeman, which was filmed at London's Royal Albert Hall in July 2008 as part of the BBC Proms.
