In Tokyo, a young woman is exposed to the same mysterious curse that afflicted her sister. The supernatural force, which fills a person with rage before spreading to its next victim, brings together a group of previously unrelated people who attempt to unlock its secret to save their lives.
It's 1969. The conflict in Viet Nam has exploded to immeasurable proportions, and 18-year-old Dean Hill's number is up. Dean's brother Eric, who has already seen his share of combat, plans to take Dean to enlist in his beloved Marine Corps in hopes of keeping an eye on him rather than letting him take his chances at the local induction center. But Dean plans to confront Eric about dodging the draft after the boys and their respective girlfriends, Bailey and Chrissie, head across Texas for a final fling of serious fun. Soon after their journey begins, the foursome are spooked by a menacing pair of bikers, Holden and his girlfriend, Alex. When Alex chases the group's jeep, propelling them into a serious accident, Chrissie is thrown from the vehicle. As Alex attempts to rob the injured trio, Sherriff Hoyt arrives and turns the tables on their would-be assassin. While Chrissie hides in the nearby brush, she watches as the sheriff kills Alex in and then taunts her friends before ordering them into the back of the patrol car. Unbeknownst to Chrissie, Hoyt is headed to the Hewitt family home where Thomas, who is being groomed to become the terrifying monster known as Leatherface, and the rest of the Hewitt clan await. Chrissie attempts to convince Holden to help her, but he is on a one man rampage to avenge his girlfriend's death. As Chrissie witnesses the horrors inflicted by the Hewitt family upon the people she loves, she realizes she is their only hope of survival.
