 After a heated argument with her military police turned cop husband, Lawson Russian immigrant house wife, Lara storms off into the night convinced he s more married to his job than her. On her drive to a friend s house, she takes pity on a mournful hitchhiker Justin Mckay, desperately searching for a ride. Her offer of a lift to him plunges her into a night of pure terror as Justin is seriously disturbed, twisted by a tortured childhood which ended in being made to see his little sister s shocking murder and mutilation at the hands of his brutal alcoholic mother (who took a butcher knife to her head and used it like a comb) who systematically slays anyone who harms or offends him on a murderous impulse, as he captures their dying moments on his Polaroid camera. As Lawson struggles to follow Lara despite a leg in plaster, he is left for dead by our Justin, but recovers and now must search the steadily darkening roads for Lara, while her deeply troubled captor Justin continues his uncontrollable slaughter-spree, rampaging through the night leaving behind carnage and fiery devastation on his path of madness.
