Amanda Abbington, Reece Shearsmith & Frances Barber star in Steven Moffat's satirical play.
To celebrate 20 years of marriage, middle-class English couple Peter and Debbie head off on a cruise. While onboard, Peter strikes up a conversation with Elsa Jean Krakowski - an American passenger who enjoys sharing her not-so-woke views on Donald Trump. They agree to stay in touch because no one really does, do they?
A few months later, Elsa invites herself over to Peter & Debbie's home to stay for a couple of weeks. But when Debbie googles their house guest, the search turns up a hair-raising truth of who Elsa really is - challenging their good natures like never before.
Award-winning writer Steven Moffat & director Mark Gatiss ('Doctor Who', 'Sherlock') bring this new comedy to the West End after a sold-out run at the Chichester Festival Theatre.
