Bill is moving in with some friends and they’ve found the perfect house – so what if it’s strangely cheap to rent, and the landlord is a little creepy?

The Doctor is played by Peter Capaldi, Bill by Pearl Mackie and Nardole by Matt Lucas. David Suchet guest stars at the Landlord.

“Knock Knock” is written by Mike Bartlett and directed by Bill Anderson.
