I saw it years ago and I remember it being pretty bad. The whole premise is that this American soldier falls in love with a Vietnamese sex worker, they sleep together and conceive a child and now the Vietnamese woman yearns to escape the evil communist country and be reunited with the man she had a fling with, but is hopelessly in love with. The whole time, this Vietnamese guy, who was initially a soldier in the NVA, then became a commissar in the post-war government is an asshole to her because he's a communist and doesn't like that she had feelings for some American guy. Anyway, the couple gets reunited in Thailand or some shit, but the American has married some other woman in the states which means that this Vietnamese woman has no other purpose in life and commits suicide because this is some Grade-A white savior complex shit or something like that
