Speed (Ross Hagen) is the leader of a rowdy biker gang who reluctantly leaves his girlfriend, Donna (Jill Woelfel), behind when the boys take off on an extended run. While waiting for their men to return, the girls take to the road on their own motorcycles and look for action. After avenging a fellow sister's rape and sexually assaulting a reluctant farmboy, the ladies evade the law and hide out at the Spahn Movie Ranch. The ranch is inhabited by a sinister hippie cult led by the charismatic King (William Bonner), who preaches peace and love but is involved in some illegal activities that he's willing to kill for. Meanwhile, the bikers are living it up, having a raucous stag party in the woods complete with beer drinking contests and fistfights. When Terry (Vicki Volante) dies after sleeping with King, Margo (Regina Carrol) knows she has to escape and get help from Speed and the gang. King decides to sacrifice Donna in a weird ritual meant to protect the "philosophy" of the cult, while the bikers race to her rescue. With fists blazing, they make short work of the evil hippies, but King escapes and it's up to Speed and his brother, Turk (Preston Pierce), to exact the proper revenge. ~ Fred Beldin, Rovi
