Nick Gunar is a burnt-out, jaded and hard-up former mercenary who is having a difficult time adjusting to civilian life. At the end of his rope, he is hired by the Nitro Mine Corporation to strong-arm the natives of a South China Sea island into giving up their rights to its valuable mineral resources. Nick loathes the thought of another mission, but this seemingly easy job will earn him enough money to get back with his estranged family. He recruits some of his former mercenary buddies to help him with the job. The island people refuse to give up their land and Nick decides to help them fight the greedy corporation that hired him. As greed and treachery begin to unravel, Nick's band of mercenaries choose sides.

The year is 1974, and Barbara Dean (Judi Dench), a British assistant manager in a foreign bank in Saigon, begins a relationship with American Bob Chesneau (Frederic Forrest). She quickly realises that he works for the CIA and he knows that the fall of South Vietnam is very near.

A group of working-class friends decide to enlist in the Army during the Vietnam War and finds it to be hellish chaos -- not the noble venture they imagined. Before they left, Steven married his pregnant girlfriend -- and Michael and Nick were in love with the same woman. But all three are different men upon their return.
