Square, uptight couple Paul [Bartel] and Mary [Woronov] have been saving money from their retail and nursing jobs to open an old-fashioned restaurant. Their realtor is coming over for dinner, but a swinger comes into their apartment by accident, Paul punches him and he dies. After a financial setback they realize they can get the money they need by attracting more swingers to their place, then killing and robbing them – “This city is full of rich perverts.”
They take pervert lessons from Doris The Dominatrix, and cut in Raoul the locksmith after realizing he’s a criminal, saving spare keys to apartments with new locks so he can rob them later. After Raoul seduces Mary, Paul follows him around and learns Raoul has been making even more money off the dead swingers, selling their bodies to a dog food company and their cars to a chop shop. Paul gets even and serves Raoul when the realtor comes over to make the deal for their new place.
Loan officer “Mr. Leech” (Buck Henry) getting fresh:
How is this movie so good? Obviously made by weirdos who chose to play the straight roles. Every normal-seeming person is a pervert in their spare time, and every professional pervert (like Doris The Dominatrix, and eventually Mary) is perfectly wholesome at home. Would make a good double bill with Parents.
