The Pinehill Crest Hotel in Kent is host to three very different events: a cross-stitch convention, an experiment in time travel and...the summoning of the scourge.

The Doctor, Bernice and Ace find themselves dealing with a dead body that's come back to life, a mystical symbol that possesses its host and a threat from another universe that's ready for every trick the Doctor's got up his sleeve. This time, has the Doctor gone too far?

Written by Paul Cornell. Directed by Gary Russell.
