Am Wannsee ist der Teufel los 1981 on netflix

Young folks from different groups of early 80s subcultures (Punks, Rockers, Poppers) are heading for Wannsee, a local recreation area in West Berlin, where they are getting in conflict with middle-class-citizens. The movie is a collection of short sketches leading to a crazy pursuit and a lunatic struggle of nearly everybody against nearly everybody.
