Angel Unchained (1970)
Director: Lee Madden
Stars: Don Stroud, Luke Askew, Larry Bishop, Tyne Daly, T. Max Graham
You can try to leave your old life behind for a more contemplative existence, but there's always gonna be a gang of dune-buggy riders waiting in the wings to hold you back.
Not much can compel a biker gang to join forces with a group of hippies, but when buggy-riding ranchers start to cause problems, Angel must unite the two groups, who wear their hair long for very different reasons, to defeat a common foe.
