A murderous car wreaks havoc on a small Western town in this thriller that has gone on to achieve a small degree of cult status in spite of its own silliness. After a pair of bikers and a horn-playing hitchhiker are viciously mowed down, local police realize they have a motoring maniac on their hands. In a show of boldness, the mysterious black automobile kills the sheriff (John Marley) on the town's main street, leaving the post to officer Wade Parent (James Brolin). A supernatural element enters the picture when the car motors through a parade practice, but refuses to enter the hallowed ground of a cemetery. The cops chase the car through the desert, but it takes out several squad cars and disappears after injuring Wade. Things take a personal turn when the car eliminates Wade's girlfriend Lauren (Kathleen Lloyd) in a shocking sequence. Gathering his remaining officers, Wade concocts a plan to stop the horsepower-laden psychopath.~ Patrick Legare, All Movie Guide
