In August 1961, the former Foreign Legionnaire, King, has collected a gang of hooligans with whom he creates mischief in the GDR. After some careless work on a construction site that leads to two deaths, the gang moves to a campsite on the Baltic Sea. With sputtering mopeds, loud radios, and occasional outbursts, they make the vacationers' lives a living hell. Unfortunately for them, Lieutenant Czernik discovers their connection to the accident at the construction site. To stop them from fleeing to West Berlin, Lieutenant Czernik and the police need to arrest them, one at a time, saving King for last.
