Special Forces colonel James Braddock (Norris) reluctantly returns to Vietnam after the war on a fact-finding mission to search for MIA's. He himself spent 10 years in a North Vietnamese labor camp until he led his men in a daring escape. He enlists the aid of State Dept. official Ann Fitzgerald (Kasdorf) and slips away to find the location of the MIA prison camp. From Bangkok, with the help of his old Army buddy Tuck (Walsh), now a smuggler, he mounts a rescue expedition.
