Rambo: First Blood Part II is a 1985 action film. A sequel to 1982’s First Blood, it is the second installment in the Rambo series starring Sylvester Stallone, who reprises his role as Vietnam veteran John Rambo.
Picking up where the first film left, the sequel is set in the context of the Vietnam War POW/MIA issue; it sees Rambo released from prison by Federal order to document the possible existence of POWs in Vietnam, under the belief that he will find nothing, thus enabling the government to sweep the issue under the rug.
John Rambo is removed from prison by his former superior, Colonel Samuel Trautman, for a top-secret operation to bring back POW’s still held in Vietnam. Rambo’s assignment is to take pictures of where the POWs are being held, but Rambo wants to get the POWs out of Vietnam. Teaming up with female Vietnamese freedom fighter Co Bao, Rambo embarks on a mission to rescue the POWs, who are being held by sadistic Vietnamese Captain Vinh and his Russian comrade, Lieutenant Colonel Padovsky. Rambo falls in love with Co Bao, and when Co Bao is killed by Captain Vinh, Rambo wants revenge.
