A modern-day Joan of Arc takes to the road in this unusual teen story. Helen Slater stars as Billy Jean Davy, the pretty older sister of the mischievous Binx (Christian Slater). When Binx's beloved motor-scooter gets trashed by the spoiled son of a local shop owner, Billy Jean demands payment for the damage. Smarmy shop owner Pyatt (Richard Bradford) agrees, only to lure Billy Jean to an upstairs room where he attempts to rape her. Injuring Pyatt, the brother- and sister-duo go on the run with some trailer-park friends, cutting across Texas while making a name for themselves as local heroes. Implausible at every turn, the film is memorable though for Helen Slater's spunky performance.
