Rambo is flown into the country with the purpose of parachuting into the jungle, but a malfunction during his exit from the plane causes him to have to cut away much of his equipment. He then meets his in-country contact, anti-communist Vietnamese rebel Co Bao (Julia Nickson), who is serving as an intelligence agent. Rambo discovers that there are POWs being held in the camp where he was dropped and that POWs were rotated between camps. Rambo breaks one POW out of the camp and attempts to escape, only to be abandoned at the moment of a pick up by helicopter on a hilltop on the orders of Murdock, after which both he and the POW are recaptured by the Vietnamese soldiers. Rambo is immobilized in a pit of sewage and leeches, then tortured by Soviet soldiers, who are allied with the Vietnamese and training Vietnamese soldiers. Co enters the base under the guise of a prostitute for hire, where she aids Rambo in escaping. After Rambo expresses his deepest gratitude for his rescue, the two share a kiss, after Co implores him to take her back to America with him. As they prepare to move on, Co is shot by surprise gunfire.
