The play is set behind the doors of the Prime Minister's residence at Number 10, Downing Street during three of the most pivotal days in British history when, extraordinarily, giving in to Hitler was considered by some to be a viable option. Having urgently assembled the British war cabinet, the new Prime Minister Winston Churchill is suddenly confronted with an intense game of political chess as he tries to persuade peace treaty supporters, including Neville Chamberlain, that Britain must fight to the death. Divided on whether to negotiate terms through Mussolini or escalate the battle against fascism alone, one man has to make a monumental decision which will shape the future of the free world.

The play, which is directed by Alan Strachan and produced by Bill Kenwright, also stars Jeremy Clyde as Lord Halifax and Robert Demeger as Neville Chamberlain.

Clarke's credits include Jim Flynn in the BBC hit TV series "In With The Flynns," three series of "Down to Earth" (starring opposite Pauline Quirke), " Blackadder," "Bleak House" and playing Dalziel in 12 series of BBC TV's "Dalziel and Pascoe." His films include Stanley Kubrick's "A Clockwork Orange" and Clint Eastwood's "Firefox."

Clyde has starred in such films as "Doctor Zhivago," "Kaspar Hauser" and "The Musketeer." His TV credits include "Downton Abbey," "Ashes to Ashes" and "EastEnders." He is also well known as half of the 60’s singing duo Chad and Jeremy, who had several big hits on both sides of the Atlantic. They recently celebrated 50 years of songwriting.
