Elmo Rocco is a professional and ruthless contract killer who operates with a strict set of rules, and whose jobs never hit the morgue. Mark , a banker, loves Suzanne, his fiancée, and wants to marry her. Suzanne loves Mark, but she also loves Rocky. Mark sees Rocky as an obstacle to his marriage to Suzanne, and hires Elmo to kill him. Elmo has had it with love-triangle jobs, but the promised money for the job on Rocky, forty thousand dollars, is very appetizing.
