Six Americans did not come home when the North Vietnamese returned American POWs at the end of the Vietnam War. They had never been reported as POWs and were listed as MIA. Their captor, NVA lieutenant colonel Pham used the Americans as laborers in his heroin factory. His goal: keep them alive and ransom them for millions.
Back in the U.S., Janet, wife of one of the POWs, was an anti-war activist who filled her waiting time and sexual needs by becoming a highly paid assassin, taking on high value targets around the world.
In 1978, the six POWs were declared dead. In 1982, the U.S. learned of their existence and rescued them in a daring raid. Back in the States, two men, one a former POW and the other a CIA operative, want the POWs dead because what they know will send the two to prison. Through her agent, Janet is hired by them to take out her husband — a bad decision on the part of the two men.
