Sheriff Hooper (Thom Barry) races to the Sawyer farmhouse, where hulking Jed Sawyer has run amok with his beloved chainsaw.
A tense stand-off spirals out of control when Burt Hartman (Paul Rae) and his gun-toting posse arrive at the scene and torch the house with the family still inside.
Gavin Miller (David Born) and his wife Arlene (Sue Rock) steal the last surviving Sawyer baby from the farm and claim the child as their own. Two decades later, Heather (Alexandra Daddario) discovers the truth about her adoption.
She heads to her hometown with her boyfriend and friends. En route, they pick up a hunky hitchhiker.
Alas, the out-of-towners unwittingly stumble into a bloody battle for survival against Leatherface (Dan Yeager).
