Meanwhile, Heather and Barry leave with Jenny, who loses them.Vilmer, a backwoods man with a robot leg, eventually arrives at the scene of the crash, where he snaps the unconscious driver's neck and chases Sean in his pickup, eventually running him over. Meanwhile, Heather and Barry come across a dilapidated farmhouse, where Barry looks for a way inside to use the bathroom while Heather waits on the porch. Barry is discovered by Walter, Vilmer's brother. While Heather waits on the porch, Leatherface appears, playing with her hair and then chasing her. After Leatherface catches her, he stuffs her inside a meat locker. While Barry is using the restroom, he discovers human remains in the bathroom, and Leatherface bludgeons him to death with a sledge hammer. After killing Barry, Leatherface removes Heather from the meat locker, hanging her on a meathook in midair.Jenny arrives back at the wreckage, only to find her boyfriend and the driver absent. She meets Vilmer, who shows her the bodies of Sean and the Driver. Vilmer then chases her in his truck, only for her to escape into the woods. After hiding in thicket, Jenny is attacked by Leatherface, wielding a chainsaw; he chases her through the woods, and back to the Sawyer house, where Jenny locks the door, but Leatherface begins to break it down by sawing through the wood panels. Jenny then discovers the remains of a Texas Ranger after taking refuge upstairs. She takes the Ranger's gun, attempts to shoot at Leatherface, but discovers that it has no bullets. Leatherface chases Jenny back upstairs, where she jumps out a window, and onto the roof. Jenny tries to use a telephone cable to escape, but Leatherface cuts the cable and Jenny crashes through the roof of the Sawyers' greenhouse. Jenny retreats back into the forest and arrives back at Darla's office, begging for help.Walter shows up and it turns out that Darla and Walter are in cahoots. Walter beats Jenny with an electric cattle prod, stuffs her in a gunny sack and then into Darla's trunk. W.E. leaves Darla to go pick up some pizzas she ordered earlier with Jenny in the trunk of her car. After getting the pizzas, she returns home with Jenny.The family terrorizes Jenny, who escapes into Darla's car, but is subdued by Vilmer, who jumps on the hood of the car. Jenny wrecks and is dragged back inside the house where she is treated by Darla, who gets her ready for dinner time. Jenny falls unconscious, but awakens in the early morning hours at a dinner table, clean and redressed in a skimpy pageant gown, with a cross dressed Leatherface, the family's apparent Grandpa (possibly an elderly Drayton Sawyer), and a family of stuffed corpses. Jenny screams in terror and soon the family is joined by a mysterious Rothman, who tells the family that they aren't doing their "jobs" correctly. Rothman makes an idle threat to Vilmer, and then takes his leave. After Vilmer crushes Heather's skull in anger, Jenny tries to escape, but is held down by Vilmer as Leatherface revves his chainsaw, preparing to behead Jenny.As Vilmer holds Jenny down, and Leatherface makes pathetic attempts to decapitate her, she manages to snatch Vilmer's remote to his cybernetic leg and uses it to dislocate his knee as an advantage to escape, which she succeeds in doing. Jenny escapes to the main road, with Leatherface in hot pursuit, where she is helped by an elderly couple, but the couple's RV is soon turned over by Vilmer and Leatherface. Jenny climbs out of the wreckage, barely harmed, and Leatherface and Vilmer pursue her on foot. An apparent "Order of the Illuminati" airplane operated by one of Rothman's colleagues, swoops over head and the blade grazes Vilmer's skull, ultimately killing him. Jenny watches as Vilmer finally dies while Leatherface screams in horror and frustration, grieving the loss of his elder brother.A black limousine appears, and Jenny enters it only to discover Rothman inside. Rothman tells Jenny that her experience was supposed to be spiritual, but that it went awry and that Vilmer had to be stopped. She is dropped off at a hospital, where she sees a mysterious blonde woman being wheeled down a corridor as police question her.Meanwhile, Leatherface swings his chainsaw in frustration, where the screen cuts to black and the credits roll on.
