The peace of tranquillity of Santa Ynes, Utah, is shattered when the town becomes the focus of several hit and run deaths, by a mysterious and apparently driverless, black car. After the Sheriff (John Marley) is run down, it is down to Captain Wade Parent (James Brolin) and his deputies to protect the town from this sinister threat. Is the car simply a driven by a mad man or is there a more supernatural explanation? When the car menaces a local school marching band, the teachers and students take refuge in the nearby cemetery. Does the cars inability to enter consecrated ground provide a clue to its otherworldly origins and offer a potential solution? As the death count increases and the population becomes more fearful, the Captain and his team of deputies form a desperate plan to see if they can lure the car into a trap.
