The Doctor and Rose Return
Sinister masked Santas and a killer Christmas tree provide some festive fear as David Tennant assumes the role of The Doctor.
At the end of the last series, viewers witnessed the start of the regeneration process and the Doctor is still undergoing this process as the Christmas special begins.
A British space probe, on its way to Mars for a Christmas Day landing, has gone missing. It has been kidnapped by a monstrous race known as the Sycorax, who are set on taking over the world.
The Doctor is lapsing in and out of consciousness and Rose (Billie Piper) feels powerless as she tries in vain to find a remedy that will get him back on his feet.
The adventure is followed by a special interactive episode on BBCi (digital viewers only). Press ‘red’ after The Christmas Invasion.
The Christmas Invasion airs 7pm tonight, December 25th, on BBC One.
