On August 18, 1973, five young adults—Erin Hardesty, her boyfriend Kemper, and their friends Morgan, Andy, and Pepper—are traveling through the Texas countryside after a trip to Mexico to buy marijuana, headed to a concert with a sense of casual adventure. Their drive takes a dark turn when they pick up a traumatized hitchhiker who insists they’re going the wrong way and mutters about “a bad man” before pulling out a hidden revolver and ending her own life in front of them. The mood shifts from uneasy curiosity to uneasy fear as the group contemplates what they’ve just witnessed and what it might mean for their safety.
Desperate to contact the authorities, they stop at a remote gas station run by a wary, no-nonsense woman. The proprietor directs them to meet Sheriff Hoyt at the old Crawford Mill, but the encounter takes a puzzling and sinister turn almost at once. A young boy named Jedidiah greets them and claims Hoyt is not where he should be, but rather at home drinking. Erin and Kemper venture into the surrounding woods to locate Hoyt’s supposed residence, leaving Morgan, Andy, and Pepper behind at the mill with the boy. Their search leads them to a decaying plantation house, where a local character named Monty permits Erin inside to make a call for help, while Kemper investigates further.
Inside, danger unfolds swiftly. As Kemper moves through the house, he’s knocked unconscious by an unexpected assault, and a masked figure known as Leatherface drags him away toward a basement. Erin, left outside, learns that Hoyt has arrived and begun taking control of the hitchhiker’s body, darkly complicating the situation and heightening the sense that something monstrous is orchestrating the night’s events. Erin’s resolve hardens as she and Andy reconnect and begin to search for Kemper, while the house and its occupants reveal themselves to be part of a grim family’s pattern of violence.
A tense moment follows when Monty distracts Erin, allowing Leatherface to appear again. Andy encounters this terrifying figure as well, and a brutal chase ensues. Leatherface slams into action with a chainsaw, striking fear into anyone who stands in his path. Andy fights back, but is ultimately overwhelmed, and Leatherface completes a gruesome assault by removing Andy’s left leg and dragging him toward a basement where he is impaled on a meat hook. Erin, who had managed to escape to the mill earlier, returns to the house only to confront Hoyt, who remains outwardly calm even as the danger escalates. Hoyt calls for a grim reenactment of the hitchhiker’s suicide, Handcuffs Morgan and drags her back toward the house, while Pepper and Erin face the relentless threat of Leatherface.
The chaos intensifies as Leatherface — now wearing Kemper’s face as a mask — attacks Pepper and forces Erin to flee. Pepper is killed in the shock of the encounter, and Erin seeks safety in a nearby trailer owned by the Tea Lady, a large, imposing woman who, with Henrietta, provides tea that appears to be laced with drugs. Erin discovers that the Tea Lady and Henrietta have abducted the hitchhiker’s baby, and she nearly escapes before succumbing to unconsciousness. When she regains consciousness, she finds herself surrounded by the Hewitt family: Leatherface, Luda Mae (the matriarch), Hoyt, Monty, and Jedidiah, all bound together by a shared, brutal conspiracy.
In the basement, Erin discovers Andy still alive but unable to move, hanging on a meat hook. She must make a harrowing decision to end his suffering with a knife when she cannot lift him to safety. She then stumbles upon a wounded Morgan, who is handcuffed in a bathtub, and the two flee as Leatherface closes in with brutal efficiency. Jedidiah, who disagrees with his family’s cruel acts, helps create a distraction that allows Erin and Morgan to break free and flee into the woods, seeking shelter in an abandoned shack. Leatherface tracks them, and the pursuit becomes a ferocious cat-and-mouse sequence that culminates in a violent assault on the shack.
Morgan is killed in the ensuing confrontation, hanged from a chandelier by his handcuffs as Leatherface closes in on Erin and the chase resumes into a slaughterhouse setting. Erin fights for her life with grit and resourcefulness, eventually using a meat cleaver to sever Leatherface’s right arm in a climactic struggle. Gripped by fear yet determined, Erin exits into the open and flags down a trucker in a bid to escape in the same way the hitchhiker did earlier. The trucker stops to seek help at the gas station, while Leatherface lurks nearby, and Henrietta remains close to the van and baby.
In a desperate move, Erin seizes the hitchhiker’s baby and places the child safely in Hoyt’s car, hoping to carry the infant to safety. She hot-wires the car and drives away, repeatedly colliding with Hoyt as Leatherface appears in the road, slashing the vehicle with his chainsaw. Despite the danger, Erin manages to escape with the baby in tow. The aftermath is bleak: two days later, two officers who investigate the now-abandoned house encounter Leatherface, who kills them as the case remains unsolved and unresolved.
Throughout this harrowing odyssey, the film maintains a stark, unflinching tone that emphasizes vulnerability, predation, and the collapse of any sense of safety when confronted with a family whose brutality seems bound to the land itself. The tension rests not only on physical danger but on the psychological strain of mistrust, misdirection, and a night that spirals from a routine road trip into a nightmare that refuses to end. The result is a grim, raw meditation on fear, survival, and the unsparing darkness that can dwell behind closed doors.
