Driving through Texas, young yuppie couple Michelle (Kate Hodge) and Ryan (William Butler) stop at the Last Chance Gas Station, but after they witness the owner attacking a hitchhiker named Tex (Viggo Mortensen), they panic and flee. In their hasty departure, they get lost and soon find themselves pursued by the chainsaw-toting maniac known as Leatherface (R.A. Mihailoff). While running, the couple bump into survivalist Benny (Ken Foree), who they team up with in an effort to escape.
