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 Doctor and Ruby Sunday travel through time and space on adventures to unknown lands, to the Regency era in England, to outer space worlds and the sixties.

The fictional world of Royston Vasey is facing apocalypse and the only way to avert disaster is for our nightmarish cast of characters to find a way into the real world and confront their creators. From present day Soho to the fictional film world of 17th Century Britain, the residents must overcome countless bizarre obstacles in their bid to return Royston Vasey to safety.
