Heinrich Lutter (Götz George) is an unemployed locksmith. He lives with his two sons Mike (Markus Knüfken) and Günni (Bastian Trost) in Cologne, Ehrendfeld - a worker's district. Both need his unrestricted attention: Mike has a police record and Günni is mentally handicapped from birth. His only stability is his camper - for him it is a symbol of liberty and a fulfilled life in Italy. But his dream "on four wheels" is confiscated by public authority. Although, Heinrich Lutter stands firm. He is convinced that he attained it by honest means, and is determined to realize his visions of the future. Mike's conflicting convictions and his criminal machinations puts the timid approximation to a severe test in this sensitive narrated environmental study.
