Das Geheimnisvolle Wrack plot
Wolfgang is from Berlin and is currently visiting the Baltic Sea. He plays with the children in a blown up bunker on the beach. When the kids discover an old wreck off the coast, they are curious and want to explore it. Wolfgang also finds this much more exciting than the bunker. One night they take a boat trip to investigate the mysterious wreck. But the venture is anything but innocent, because the boys are surprised and detained by gangsters who use the wreck as a base to smuggle explosives to the GDR. When an action begins by the police, who have been aware of the smuggling for a long time, they find the boys in critical condition.
