 On August 18th, 1973, in Texas, the youths 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 to a concert of the Lynnard Skynnard. Kemper is driving his van, when they see a disturbed young woman dangerously wandering on 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.
