29-year-old Benz lives in Freiburg and delivers vegetables throughout the Black Forest. His delivery round, carrying cabbages, salad and turnips around Neumünster, Todtnauberg and Kirchzarten seems to satisfy his ambition. But then he meets capricious Theres, and she turns his life upside down. From that point onwards, Benz comes up with all sorts of offbeat schemes and dreams up the most unfeasible fantasies to win her over. Eventually she lets him sleep with her, but in the morning she vanishes into thin air. Benz has to reassess his life from the ground up, leaving his happy-go-lucky past and his easygoing modesty behind.
