Early in 1939 Sir Robert Thorndyke takes aim at Adolph Hitler with a high powered rifle, but the shot misses its mark. Captured and tortured by the Gestapo and left for dead, Sir Robert makes his way back to England where he discovers the Gestapo has followed him. Knowing that his government would turn him over to German authorities, Sir Robert goes underground in his battle with his pursuers. The plot is marvelously gritty, with a brutal struggle for survival and a sense of desperation rarely seen in British films. Made for BBC Television.
