In Regency England, beneath the frozen Thames, something is stirring.
The Doctor and Bill arrive at the last of the great frost fairs, and find themselves investigating a string of impossible disappearances – people have been vanishing on the ice! Bill is about to discover that the past is more like her world than she expected, and that not all monsters come from outer space…
