Two couples on a picknick are surrounded by a bunch of bad-boy bikers, and are abused and beaten. But the muscular Frank gets a bullet-proof vest and a .44 magnum, and goes biker hunting to get even. Thora Birch’s parents are in the lead roles of this shot-in-Florida biker/revenge flick, that’s so cheap and sleazy and amazingly godawful that it’s a sick delight from beginning to end.
