Attempting to rescue a wounded soldier, Sergeant Brent is himself seriously injured and left to die by heartless commanding officer Tony Marsina who has a habit of taking decisions that lead to injury or death of his men. But Green Beret Brent is not about to die just yet: he spends several grueling days hacking his way through the jungle, for the express purpose of beating Marsina to a pulp.
Which he does and is therefore arrested by the MP facing a court martial. During an attack of the Vietcong the vehicle he is transported in is damaged and Brent escapes to the wilds of Cambodia, where he determines to live out the rest of his life. But the duel of the two men is not yet over.
