The episode will fittingly take place as the new year begins in the Doctor Who universe.
Unsurprisingly, the Doctor and her friends will kick off their new year with a frightening adventure through time.
Unless Doctor Who is using this latest preview to misdirect fans (in what would be a rather unkind move considering that this would be the last episode for at least a year), the Daleks — or at least a Dalek — will menace the Doctor and Co. in the New Year’s special.
