Rocker (1972)

After serving time, Hamburg rocker boss Gerd returns to find his girlfriend with Uli, a car thief. When Uli is killed by pimps, his 14-year-old brother Mark spirals into self-destruction. Sent back to the countryside, Mark instead crosses paths with Gerd, aiding him in a drug deal—and earning his protection. A street-level portrayal of Hamburg’s vanished biker subculture, featuring non-professional actors and capturing the city’s gritty underbelly with unfiltered authenticity.
