 Chris, a radio DJ, and his wife, Katrin, who works at a truck stop, are friends with Uwe, who owns a snack bar, and his wife, Ellen, who sells perfume. Chris initiates an affair with Ellen; Katrin walks in on them while they are bathing together. Each of the principals has a radically different way of dealing with it. Meanwhile, Chris s radio horoscopes seem oddly personal, and the street musicians outside Uwe s restaurant keep getting more numerous.
