Fuller, Texas. Summer 1972.
Three escaped convicts, along with a few girls along for the ride, are joy riding across rural Texas robbing banks, heading for Mexico. When they stop to rob the Hewitt family General store, they enter a horrifying world of madness and depravity that even a maximum security prison couldn't prepare them for as Leatherface, Sheriff Hoyt, Old Monty and the entire Hewitt clan hunt them down.
It gets messy.
