The film opens with Colonel Samuel Trautman (Richard Crenna) offering Rambo his freedom if Rambo will return to Vietnam to search for American prisoners of war remaining in Vietnamese captivity. Marshall Murdock (Charles Napier), the official in charge of the mission, is portrayed as a corrupt political figure who doesn't want to expose the truth. Rambo is not to engage the enemy and instead is ordered to take photographs of a North Vietnamese camp, the same camp he himself had been held prisoner in, to prove to the American public there are no more POWs in Vietnam, although Murdock knows that there are.
