On this island, however, the passionate fisherman Michael Lutz and his somewhat neglected admirer Barbara Holstein already spend their vacations.Michael asks the singer Bob Stuart, together with his band in their ghost costumes to drive away the annoying newcomers again. However, it no longer comes to this, because on behalf of Gina, the wife of the local police chief, real gangsters appear with the tourists and finally flee with their dinghy. So now the vacationers have to rely on each other willy-nilly, and the couples finally find each other.
