Rich socialites Jean and Danielle are experiencing marital problems. Jean hears a woman being assaulted in the apartment above and investigates. He encounters Nicole, a seemingly frightened woman who is under the control of her domineering boyfriend Klaus, and is drawn into a relationship. However it emerges that Nicole was used as bait in a trap set by Klaus, who was apparently paid $20,000 to kill Jean. In the meantime, Nicole claims to have actually fallen in love with their victim, but Klaus kills Jean and burns the body to make it look like he died in a car accident.
