Gentlemen in White Vests（1970）

Bruno Stiegler, a boxing promoter with a disreputable past, returns from America to Berlin to make some big things again with his friends. Fatally, he is always preceded by some gentlemen from better circles who are developing amazing criminal activity in their old days. They are led by Oberlandesgerichtsrat a. D. Herbert Zänker, whom it still hisses, that he could bring in his term Bruno never behind bars.
