With all of her friends dead, Erin (Jessica Biel)escapes the abandoned shack and runs to the meat factory, but Leatherface finds her. She escapes the meat factory after chopping off Leatherface's arm. She is picked up by a truck, who then brings her back to the old gas station. Erin leaves the truck and rescues the stolen baby. She hijacks the sheriff's car and runs the sheriff over until he is dead. She then races off down the road in the car (with the baby). The car is chainsawed by Leatherface, but Erin continues to drive. We never really find out if Erin lives or dies. The two cops that were investigating the crime scene at the begining of the movie are killed by Leatherface.
