Alex and her friends Trey, Sophie and Brent go into the woods of West Virginia on a rafting trip. As they are camping, Alex’s friends are killed by Three Finger. Sheriff Carver and Deputy Lane receive a report about the missing group.
Two days later, prison guard Nate is assigned with Walter and Preslow to transfer a group of prisoners to a distant prison. The prisoners are Crawford, a car thief; Floyd, a neo-Nazi serial killer; Brandon, who was wrongly convicted of murder; Chavez, the leader of a crime organization; and Willy, an undercover agent who is posing as a prisoner to get information from Chavez. While driving, their bus is rammed by Three Finger’s truck and crashes in the woods of West Virginia, forcing them to continue on foot. Walter is badly injured, but Nate rescues him from the truck before it explodes.
They follow Alex, and on the way, find an abandoned armored truck. Chavez tells Nate to check the cab of the truck. Nate finds a set of keys and a gun. He secretly gives the gun to Walter, after handing the keys over to Chavez. Chavez uses the keys to open the back of the truck, and finds several bags of money. He intends to steal the money and demands that everyone carry two bags, but Walter refuses because of his injury. In a last-ditch effort to regain control of the situation, Walter pulls out the gun and tries to shoot Chavez. Unfortunately, the gun is not loaded and Chavez shoots and kills Walter. Chavez forces those left alive to carry the money and they continue on foot.
Along the trail, they stumble upon a trap, set by Three Toes, Three Finger’s son. They escape then catch the son and behead him, leaving a trophy on the spent booby trap for Three Finger to find as a deterrent. This enrages Three Finger, who sets traps for the group, killing first Willy, then Crawford.
