After an argument outside a club, David watches as his girlfriend Sylvia storms off and climbs into the cab of Goliath, the mammoth rig of Jack, a trucker they met the night before. As Goliath roars off, Jack tosses a Polaroid photo out of the window, and David realizes that his car keys are missing and his mobile phone has been tampered with. He calls the police and discovers that a young woman is missing, the same woman as in the Polaroid. Only the woman is no longer missing - her frozen body has just been found! Jack leaves a trail of clues for David and lures him into a harrowing game of cat and mouse. But while David battles the metal demon, Sylvia must match wits with Jack to save both herself and the man she loves.
