Rambo has withdrawn to a Buddhist monastery in Thailand. His mentor Colonel Trautman asks him to help carry out a dangerous mission in Afghanistan. But the Vietnam vet refuses: he has found peace, serenity and is non-violent. Trautman attempts the mission alone. He is captured by the Soviets and is harshly interrogated by the cruel Colonel Zaysen. The CIA can do nothing and call upon Rambo. Trautman must be released. Rambo needs a few moments to choose his weapons and bind his muscles before hitting his enemies like a hurricane. In a few days he ravages the country. He fights barehanded with a well-trained giant, leads a group of freedom fighters, destroys an airborne unit and escapes unharmed from huge explosions.
