　　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.

　　When Troy Holloway wakes up to find himself trapped aboard a drifting escape pod shooting towards the Sun he quickly realises the true terror of his situation. With rapid oxygen depletion and a burn- up rate of 90 minutes, Commander Roberts leads a rescue party to save Holloway before time runs out. Having recently lost his son and now confronted by his immediate end, Holloway feels less enthusiastic about survival. But Roberts, speaking to him only through a weak radio transmission, is determined to save his life, and both soon learn that the lives they have both lived influence each other in unexpected ways.
