In 1967, U.S. Army volunteer Chris Taylor arrives in South Vietnam and is assigned to an infantry platoon of the 25th Infantry Division near the Cambodian border. The platoon is officially led by the young and inexperienced Lieutenant Wolfe, but in reality the soldiers defer to two of his older and more experienced subordinates: the hardened and cynical Staff Sergeant Robert "Bob" Barnes, and the more idealistic Sergeant Elias.
