Peter Capaldi‘s second Doctor Who Christmas special, “The Husbands of River Song,” will air today on BBC1.

‘Doctor Who’ Christmas Special

This year’s Doctor Who Christmas special will feature the Doctor hiding in his Tardis on a remote human colony to avoid the Christmas spirit. His solitude is interrupted, however, when Nardole (Matt Lucas) arrives in search of “a surgeon,” according to The Telegraph. The Doctor soon reunites with River Song (Alex Kingston), though River doesn’t know who the Doctor is and is merely tying to help King Hydroflax.

The upcoming season of Doctor Who could be Capaldi’s final in the titular role of the Doctor.

“This could be my final year – it’s terrifying. I love Doctor Who but it can be quite an insular world and I do want to do other things,” he recently told The Telegraph.

“There will come a time when this is over. But I knew that when I started. I was thinking about my regeneration scene from the outset,” he added.” That’s my terrible melancholic nature. When you accept the job you know there’ll come a day, inevitably, when you’ll be saying goodbye.”

 

“The Husbands of River Song” will air on BBC One Christmas Day at 5:15 pm.
