Renée dite Guinguette, a former prostitute, has earned enough money on the Parisian sidewalk to buy her dream: a waterfront guinguette. Her new lover, Marco, offers her the use of an unused adjoining barn to store the second-hand cars he trades in. But the "used" cars are actually stolen, and the charming Marco is a bad boy. After a few deaths and various vicissitudes, love finally triumphs.
