In 1974, the original tapes for "Power of the Daleks" were wiped from the BBC Archive. After 50 years, the BBC has animated this lost serial for a new age. In the original, the Doctor (Patrick Troughton) has just regenerated or has been "renewed". His companions, Ben (Micheal Craze) and Polly (Anneke Wills), are unsure of this new man. Is he the old man they departed London with? But the TARDIS lands on the planet Vulcan, and soon the Doctor and his companions are mixed up in the death of an Earth examiner, a colony from Earth and a rebellion against the colony's current government. But, a scientist named Lesterson (Robert James) had foolishly tampered with powers he can't control. Now, the Daleks are planning on destroying the colony, and only the Doctor can stop them!

The upcoming festive special will see the return of one of the Doctor's biggest and most feared enemies - the Daleks. The Doctor is locked away in a high-security alien prison. Isolated, alone, with no hope of escape. Far away, on Earth, her best friends, Yaz, Ryan and Graham have to pick up their lives without her. But it's not easy. Old habits die hard. Especially when they discover a disturbing plan forming. A plan which involves a Dalek.

The Eleventh Doctor is portrayed by Matt Smith. Steven Moffat took over as head writer and executive producer after Russell T Davies stepped down. Julie Gardner also stepped down as executive producer and was replaced by Piers Wenger and Beth Willis.
