John Rambo(Sylvester Stallone) is removed from prison by his former superior, Colonel Samuel Troutman(Richard Crenna), for a top-secret operation to bring back POW's still held in Vietnam. Rambo's assignment is to only take pictures of where the POWs are being held, but Rambo wants to get the POWs out of Vietnam. Teamed up with female Vietnamese freedom fighter Co Bao(Julia Nickson), Rambo embarks on a mission to rescue the POWs, who are being held by sadistic Vietnamese Captain Vinh(William Ghent) and his Russian comrade, Lieutenant Colonel Padovsky(Steven Berkoff). Rambo starts killing every enemy in sight while still focusing on his intentions to rescue the POWs. There are also corrupt American officials involved in the mission, including Marshall Murdock(Charles Napier), one of Rambo's superiors.
