A San Francisco civilian police detective is forced to work on a series of murders with his former enemy commanding officer while dating his daughter.

When a Paul enters his apartment to find Mary fighting off a swinger who has gotten into the wrong apartement (and thinks that Mary is just playing hard to get) he hits the man with a frying pan, killing him. Their dreams of running a small resturant seem to be in jeopardy until they decide to dispose of the body, keep the wallet, and to advertise for other sexually oriented visitors who are summarily killed, bagged, robbed and disposed of. This goes along quite well until one night a burglar named Raoul breaks in and cuts himself in for a piece of the action.
