As a serial rapist/strangler dubbed the Necktie Killer roams the streets of London, an innocent man whose ex-wife was one of the victims is accused of the crime and arrested. After escaping from prison, he becomes determined to get revenge─unaware that the madman he seeks is a friend of his. Based on a true series of crimes, Alfred Hitchcock's darkly funny and sexually charged shocker stars Jon Finch, Barry Foster, Alec McCowen, and Billie Whitelaw. 116 min.
