North Sea Is Death Sea(1976)

Original title: Nordsee ist Mordsee

14-year-old Uwe lives in a suburban Hamburg housing estate. Besides trouble, the boy has not much to expect from his parents. To get his hands on some money, he prizes open vending machines, and to let out his frustration, he beats up "wogs". Among them is Dschingis, his nemesis. But one day, the rivals make peace. They become friends because they realize that they have the same problems and are driven by the same dreams and hopes.
