This biker-horror oddity was directed by former editor Michel Levesque (Sweet Sugar). The plot concerns a motorcycle gang, The Devil's Advocates, led by Adam (Stephen Oliver). The bikers are turned on to Satanism by a creepy monk (Severn Darden), leading to lengthy scenes depicting various occult rituals, drug trips, and female nudity. The cycle-riding werewolf only appears in the last few minutes of the film, but cult devotees will be happy in the interim watching such minor celebrities as Billy Gray, the child star of Father Knows Best, who was fresh off a marijuana arrest, and Barry McGuire, singer of the seminal '60s protest song "Eve of Destruction." Stunt coordinator Chuck Bail went on to direct The Gumball Rally (1976) and several blaxploitation films.
