Mark Stone has a score to settle. A former Green Beret, he has only one activity that gives meaning to his life - finding American's forgotten fighting men, the P.O.W.'s the government has conveniently labeled M.I.A.'s, and bringing them back from their hell on earth. It's too big a job for one man. But Stone has friends. And with Hog Wiley and Terrance Loughlin-a merc from east Texas and a crack British commando - Stone returns to the steaming jungles of Laos on a do-or-die mission.
