Opening credits and first few minutes of this cult flick in which a dull but well-meaning couple, the Blands, dream of owning a restaurant but don’t have the $20,000 they need to do so.   One night, a swinger from the party next door enters the Blands' apartment and tries to assault Mary. Paul kills the intruder with a frying pan. The Blands discover the deceased is loaded with money and hit upon an idea: Lure sex-seekers to their home via a classified ad, kill them, and take their money. This way, they're both financing their dream and cleaning up society! When a locksmith named Raoul discovers their scheme, the Blands must make him a partner — especially since Raoul knows that the "tasty" cadavers are being disposed of in a "culinary" manner.
