Paul and Mary Bland are a straight-laced, financially struggling couple living in Los Angeles. They dream of opening their own restaurant but face overwhelming financial obstacles. Through a series of misadventures, they discover that their prudish nature and moralistic attitude give them a means of accumulating funds in a most unusual way. When Paul accidentally kills a swinger attempting to assault Mary, the couple decides to lure and prey on other perverted individuals to rob them of their money, thereby financing their culinary dream. They adopt this darkly comedic, twisted scheme as a pragmatic solution, giving in to the moral gray area for personal gain.

As their operation intensifies, they encounter Raoul, a charismatic locksmith and small-time crook, who discovers their secret. Raoul proposes to become their accomplice, offering his expertise to streamline their illicit activities for a significant cut of the profits. However, this partnership introduces complications, as Raoul's own ambitious and unscrupulous nature begins to surface, creating tension within the trio. The couple's once simplistic, if morally dubious, lives spiral into a series of escalating events that challenge their ethics and test their resolve to achieve their dream. Their increasingly tangled web of deceit and crime steadily builds towards an uncertain climax.
