The BBC have released the title, synopsis and the promotional poster, included above, for the upcoming 2015 Christmas Special featuring Peter Capaldi as The Doctor and Alex Kingston as River Song. The title has been revealed as The Husbands of River Song. The synopsis for this episode can be read below:
It’s Christmas Day on a remote human colony and the Doctor is hiding from Christmas Carols and Comedy Antlers. But when a crashed spaceship calls upon the Doctor for help, he finds himself recruited into River Song’s squad and hurled into a fast and frantic chase across the galaxy. King Hydroflax (Greg Davies) is furious, and his giant Robot bodyguard is out-of-control and coming for them all! Will Nardole (Matt Lucas) survive? And when will River Song work out who the Doctor is?
All will be revealed on a starliner full of galactic super-villains and a destination the Doctor has been avoiding for a very long time.
The Christmas Special airs on Christmas Day. The current prospective time of transmission is 5.15pm (matching The Snowman's air time) with a 60 minute slot, however this is subject to change.
