Later, they witness the monster truck run over a man, and they meet a man missing an arm who tells them the creature in the monster truck takes peoples limbs, but lets the victims live. Afterwards, the three drive through a ghost town with many scarecrows. They find a diner at the end of the town and begin to eat, but Adam finds they are eating human flesh. They panic and run away. After being chased by the man in the monster truck, their car is destroyed. Adam, Harley, and Sarah run into the woods and the man follows them. He finally catches up with them and shoves Harley into a tree, supposedly killing him, and kidnaps Sarah. Adam follows him to a shack covered with pentagrams, severed limbs, and a man whose entire middle section has been crushed. Adam finally finds Sarah and tries to escape, but Sarah knocks him unconscious. Sarah and the man, Bob, are brother and sister. They tie Adam to a table while the corpse with the crushed midsection, Fred, explains that Bob accidentally ran him over, crushing his midsection and sending Bob through the windshield. Sarah says she stitched Fred up and used black magic to bring him back to life. Fred explains that they can use other peoples limbs to add to his own body as long as the donor stays alive and they could only transfer entire bodies if the body was prepared correctly.Sarah says that they needed someone easy to prepare and Adam was the right person. Previous events begin to make sense to Adam. Everything that happened to Adam and Harley before was preparing Adam so that Fred could have his body stepping into a pentagram with a mutilated body, sleeping with roadkill, Sarah having sex with him, and eating human flesh. Adam manages to escape and kills Sarah by slashing her throat. He also cuts Fred in half when he gets up and starts to attack him. Meanwhile, Bob locks the door. ........
