A stranger, Bruno Anthony, who hates his father, approaches Guy Haines, a tennis star who hates his wife, on a train. Anthony offers a plan: each could kill the other's victim. No motive, no clue would link the two murders except for the casual meeting of strangers on a train. Haines doesn't take the plan seriously, however, until his wife is suddenly murdered and Anthony appears to demand that Haines keep his part of the bargain. Produced and directed by Alfred Hitchcock, some say it is one of his finest thrillers. Hitchcock’s daughter, his only child, Pat Hitchcock also has a role in the film.
