When Bruno (Robert Walker) meets tennis star Guy (Farley Granger) aboard a train, he confesses he wants his rich father dead, prompting Guy to reveal that he wants to divorce his shrewish wife -- so Bruno suggests that they "trade" murders. Guy laughs off the suggestion at first … until he realizes Bruno is serious. This Oscar-nominated noir from director Alfred Hitchcock also features the director's daughter, Patricia, in a supporting role.
