Rambo is released from prison and is sent back to present day Vietnam. His mission: to track down American MIAs. The plan: a parachute into forbidding jungle. With nothing but a serrated knife and a bow with arrows, he is told not to engage the enemy, just to take reconnaissance pictures. Betrayed by his own, Rambo struggles against deadly odds and vows revenge on those who made him an enemy - no man, no law, no war can stop him.
