The harassment triggers flashbacks of Rambo's memories of his torture at the hands of the North Vietnamese when he was a prisoner of war. Rambo fights his way out of the sheriff's department with his bare hands and makes his way into the wilderness. A manhunt ensues, with the sheriff and his deputies all badly wounded. Rambo chooses not to kill any of them, but unintentionally kills a police officer in self-defense by throwing a rock at a helicopter, causing the pilot to lose control and an officer to fall out. The State Police and National Guard are called in.
