A California couple and a survivalist encounter Leatherface and his family.

Driving through the backwoods of Texas, five youths pick up a traumatized hitchhiker, who shoots herself in their van. Shaken by the suicide, the group seeks help from the locals, but their situation becomes even more surreal when they knock on the door of a remote homestead. It's quickly apparent the residents are a family of inbred psychopaths, and the unlucky youths suddenly find themselves running for their lives. In hot pursuit is a disfigured, chainsaw-wielding cannibal known as Leatherface.

After the first massacre in 1974, the townspeople suspected that the Sawyer family were responsible. A vigilante mob of enraged locals surrounded the Sawyer house, burning it to the ground and killing every last member of the family. Decades later, a young woman named Heather learns that she has inherited a Texas estate from her grandmother. She decides to bring her friends along on the road trip to investigate her inheritance. On arrival, she discovers she has inherited a mansion, but is yet to uncover the terrors that lurk in the basement underneath it.
