Near the small desert town of Santa Ynez, a mysterious black car runs down two teenage bicyclers en route to camp, then it hit-and-runs a hitchhiker with local Amos Clements as witness. Sheriff Everett puts his men on alert and plants road blocks in the area to arrest the murderer, but soon he himself falls victim to the car. Sheriff Wade Parent leads the hunt for the vehicle that threatens their town and seems impossible to locate. When his beloved girlfriend, teacher Lauren Humphries, challenges the driver in a cemetery, the car hunts her in her home. Wade realizes he might be dealing with supernatural powers. 故事描述在新墨西哥州的小镇，一辆豪华轿车被魔鬼控制，成为一辆到处行凶的无人驾驶汽车。导演艾略特·席尔维斯坦（Elliot Silverstein）创造性地赋予了一辆车杀人的魔性，堪称70年代的邪典代表作之一。
