In Hamburg, West Germany, a rocker biker gang helps a kid avenge his brother who was murdered by a rival gang, a mortal enemy of rocker gangs.

Very authentic movie about life in Hamburg in the early 1970s.

Rock'n'roll, sex, drugs, 70s lifestyle, 70s hairstyle, murder, prostitution, Santana, bikers, Reeperbahn, and St. Pauli provide the basis for the story featuring Gerd and Modschiedler, the ill-assorted couple (if at all amateur actors, who act themselves) of this fantastic movie.
