Angel Unchained (1970)

After Angel (Don Stroud) decides he wants to make his own way, he leaves his biker gang and joins a commune of hippies. There he falls for free-spirited Merilee (Tyne Daly). However, trouble soon arises when a band of raucous cowboys in dune buggies harass the hippies, trying to force them off the land. Jonathan (Luke Askew), the commune's leader, asks Angel to call his biker pals to lend support. The gang arrives, but they have their own chaotic agenda.
