Recovering from the trauma of his experiences in Vietnam, a former Green Beret is offered a deal by his former commanding officer and a government official: a presidential pardon in exchange for a covert mission to confirm the existence of American POWs in Vietnam. Although skeptical, he accepts the mission with the condition that he will only take pictures as proof and will not engage the enemy, thus keeping the operation discreet. Armed with only a knife, a bow, and limited equipment, he parachutes into the dense Vietnamese jungles. Once there, he quietly begins to gather evidence of the prisoners' whereabouts.

However, the mission takes a sharp turn when he discovers that American soldiers are indeed being held captive. He defies his orders to remain undetected, choosing instead to rescue a prisoner. Betrayed by someone in his own ranks and left to fend for himself in enemy territory, he relies on his survival skills and combat prowess to evade capture by hostile forces. With the depths of the jungle as his battleground, he becomes a one-man army, determined to expose the truth and save his fellow soldiers against overwhelming odds.
