Festive edition of the time-travelling drama. The Doctor has one hour to save a crashing spaceship and a miser’s soul – but what lurks in the fog?
Newly wedded companions Amy Pond (Karen Gillan) and Rory Williams (Arthur Darvill) are trapped on a crashing space liner which has been caught in a strange cloud belt. They call the Doctor (Matt Smith), who lands on the planet below and meets the miserly Kazran Sardick (Michael Gambon), a man who can control the cloud layer but refuses to help. Inspired by Charles Dickens’s A Christmas Carol, the Doctor attempts to use time travel to alter Kazran’s past and make him kinder so he will save the spaceship.
