Upon stopping for gas and directions on the Texas back roads, bickering yuppies Michelle (
Kate Hodge) and Ryan (
William Butler) get harassed by leering service-station owner Alfredo (
Tom Everett). When the helpful intercession of a hitchhiker named Tex (
Viggo Mortensen) leads to violence, the couple flees the area. Eventually, an unknown truck forces them off the road and into an accident with the sports utility vehicle of Benny (
Ken Foree), a well-armed survivalist. Pursued by unknown assailants, Benny and his fellow accident victims must abandon both vehicles and armaments. Eventually all three end up trapped on the boggy forest estate of a family of cannibalistic serial killers who range in age from a feral little girl (
Jennifer Banko) to an aged matriarch (Miriam Byrd-Nethery). The clan also includes the title character, whose chainsaw-wielding rampages are among the few direct links between this installment and the earlier two films in this series.
