On August 18th, 1973, in Texas, Erin(Jessica Biel), her boy-friend Kemper(Eric Balfour), their friends Andy(Mike Vogel) and Morgan(Jonathan Tucker) and the hitchhiker Pepper(Erica Leerhsen) are returning from a vacation in Mexico having been to a Lynnard Skynnard concert. Kemper is driving when a disturbed young woman dangerously wanders onto the road. They decide to help her, and the woman commits suicide inside the vehicle. They decide to look for a telephone to call the Sheriff, and they end in the house of Thomas Hewitt(Andrew Bryniarski), where their lives are threatened by the sick Leatherface and his deranged family.
