The Exterminator

During a firefight in Vietnam War, U.S. soldiers John Eastland and his best friend, Michael Jefferson, are captured by the Viet Cong. They are tied to wooden stakes with several other men, and tortured for information. When Eastland refuses to answer, the VC commander decapitates the soldier beside him with a machete. Jefferson escapes moments later, kills the remaining VC soldiers, and unties Eastland. Eastland then kills the VC commander.
