Hell's Angel chronicles the origins and rise of the Hell's Angels Motorcycle Club through the eyes of its founding member. Sonny Barger started the Oakland chapter of the Hell's Angels in the late 50s with a loose-knit group of high school dropouts and social outcasts. Bonded by the love of motorcycles, they formed a cadre of hard-driving hombres and answered the call of the open road.

Hell's Angel is not only a story of motorcycles, it is a tale of loyalty and betrayal, subcultures and brotherhood and freedom. It is Sonny's fight for personal freedom and his right to exist with a band of individuals who choose an alternative life.
