This film takes place in 1952 in Vietnam and tells the story of a dissimilar friendship. The old sarcastic reporter Thomas Fowler reports from Saigon for the London "Times". There he meets the young idealistic American Alden Pyle, who joins a medical aid programme. Unfortunately Pyle falls in love with Fowlers Vietnamese girlfriend Phuong. The film combines love drama and war and uses the conflict between the two men wanting the same woman to show that Vietnam is just a playball between the different fronts like Phuong. During the fight between the two friends it becomes clear that the quiet American Pyle is a cruel CIA agent.
