Film version of the musical by the same name: Sunnie, a girl from the province, comes to Berlin to meet rock star Johnnie who had given her his address after a concert. On the subway to Kreuzberg, Sunnie becomes acquainted with a couple of strange people, among them "asphalt cowboy" Bambi. Bambi tells Sunnie that Johnnie’s address in Kreuzberg does not exist. Together, Sunnie and Bambi try to find the rock star in bustling metropolitan Berlin.
