In modern-day London, a sex criminal known as the Necktie Murderer has the police on alert and in typical
Hitchcock fashion, their trail is leading to an innocent man, who must now elude the law and prove his
innocence by finding the real murderer. John Finch, Alec McCowen and Barry Foster
head the British cast in this thriller that alternates suspense scenes with moments of Hitchcock's
distinctive black humor. The screenplay is by Anthony Shaffer.
