While driving across the country on their way to Las Vegas, two couples are forced to "borrow" a car from an apparently abandoned ranch house when their own vehicle breaks down in rural Utah. Little do they know that the car they took actually belonged to Rusty Nail, the cold, calculating killer who plays vicious and cruel games with his victims, often pursuing them in his ominous, black 18-wheeler truck. After one of their friends is kidnapped by the murderous trucker, the remaining travelers are forced into Rusty's violent realm to play his sinister cat-and-mouse games in an attempt to rescue their friend and stop the killer before it is too late.
