 Shayne (Diane McBain), the leader of a Honda-riding biker gang known as the Mini-Skirt Mob, has been jilted by her lover, cowboy star Jeff Logan (Ross Hagen) who has married straight-laced Connie (Sherry Jackson). Shayne enlists the rest of her gang to help her break up the newlyweds and get Jeff back - even if that means killing him in the process. Her revenge escalates until her sister Edie (Patty McCormack) is killed by a Molotov cocktail and Shayne finds herself hanging by one hand over a deadly chasm. Should Connie let go before Jeff returns with the police? With Jeremy Slate as Lon and Harry Dean Stanton as Spook.
