Two men are driving a refuse truck to a dump site and stop for a hamburger. Krassky (Joe Dallesandro), one of the two, strikes an acquaintance with Johnny (Jane Birkin), the girl who works in the restaurant. They swiftly become lovers. However, Krassky is basically a homosexual, and must consummate their lovemaking in a slightly unusual way. His fellow truck-driver, Padovan (Hugues Quester), is also his lover. Padovan is intensely jealous, and attempts to kill Johnny. When Krassky fails to defend her, Johnny berates him, and he and Padovan resume their journey together.
