We were the milieu! Dummse Tünn, Schäfers Nas and Beckers Schmal, Abels Män, Frischse Pitter and the Lange Tünn ... Names that still have a ring to them in Cologne. Men who came to fame and fortune through their activities in Cologne's underworld and whose stories are brutal and evil, ice-cold and hard-boiled, but also naive, quirky and above all authentic. In the 1960s and 1970s, Cologne was dubbed "Chicago on the Rhine" by the tabloid press.
