Bruno Anthony thinks he has the perfect plot to rid himself of his hated father and when he meets tennis player Guy Haines on a train, he thinks he's found the partner he needs to pull it off. His plan is relatively simple. Two strangers each agree to kill someone the other person wants disposed of. For example, Guy could kill his father and he could get rid of Guy's wife Miriam, freeing him to marry Anne Morton, the beautiful daughter of a U.S. Senator. Guy dismisses it all out of hand but but Bruno goes ahead with his half of the 'bargain' and disposes of Miriam. When Guy balks, Bruno makes it quite clear that he will plant evidence to implicate Guy in her murder if he doesn't get rid of his father. Guy had also made some unfortunate statements about Miriam after she had refused him a divorce. It all leads the police to believe Guy is responsible for the murder, forcing him to deal with Bruno's mad ravings .

|violence||A woman is stalked and then choked to death onscreen in a very sudden sequence. The murder is seen from behind a man's back, and reflected in a pair of eye glasses. A man squeezes a woman's neck and nearly chokes her, thinking he is murdering someone else. The main character is stalked obsessively by the villain. No overt violence, quite mild.|
|alcohol||Characters drink alcohol and smoke regularly,|
|frightening||The film's villain is very scary. He strangles a woman with his bare hands and pines for his own father's death. He stalks the main character with obsessive, mildly homoerotic overtones. A carousel is destroyed in the films most intense scene.|
