Doctor Who: Knock Knock Synopsis Revealed

The BBC have released the official synopsis for Knock Knock, the fourth episode of Series 10:

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 wind blows, the floorboards creak, and the Doctor thinks something is very wrong. What lurks in the strange tower at the heart of the building – and why can’t they find any way to enter it?

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

They have also announced that a ‘binaural audio edition’ of this episode will be available on BBC iPlayer immediately after it is broadcast on TV. This special version creates a 3D surround sound effect for anyone wearing headphones, placing them at the heart of the action in this nail-biting episode.

Kock Knock will air on Saturday 29 May on BBC One, with the time to be confirmed.
