After three British agents are assigned to assassinate a mysterious German spy during World War I, two of them become ambivalent when their duty to the mission conflicts with their consciences.
Secret Agent is a 1936 British spy thriller film directed by Alfred Hitchcock, adapted from the play by Campbell Dixon, which in turn is loosely based on two stories in the 1927 collection Ashenden: Or the British Agent by W. Somerset Maugham. The film stars Madeleine Carroll, Peter Lorre, John Gielgud, and Robert Young. It also features uncredited appearances by Michael Redgrave, future star of Hitchcock's The Lady Vanishes (1938), Michel Saint-Denis as the Coachman, and Michael Rennie in his film debut.
