The Unfriend

Written by Steven Moffat
Directed by Ian Robinson

Guess who’s coming… to murder?

British couple Peter and Debbie befriend Elsa while on a cruise. She’s a lusty, Trump-loving widow from Denver - less than woke, but kind of wonderful. They agree to stay in touch… because no-one ever really does, do they…?

A few months later Elsa invites herself to stay with the family in London. Looking her up, they discover her dangerous past, with a string of mysteriously deceased husbands and the police on her tail. But it’s too late - the deadly danger is already flying to England! What began as a casual holiday friendship is suddenly a threat to all their lives.

Peter and Debbie now face the ultimate challenge of the modern world - how do you protect all that you love from mortal peril without seeming a bit impolite?

A comedy from the writer of Sherlock, Doctor Who and Coupling.
