Cheung (Tony Leung) arrives in Saigon to bring his uncle and cousin (Mark) to HK. However, things are chaotic in the city. Cheung needs the help of Chow (Anita Mui) to carry out his aims, unfortunately things get more complicated when a love triangle develops between Chow and the two cousins. Things get even more complicated when they fall foul of a local general...
It isn't a bad film, the character of Mark is revisited and some important background is retro-conned but the film doesn't quite work. It's too different to the first two films and lacks the same quality of action. It probably would have been better as a stand-alone tale in Vietnam and not struggling to carry the baggage of the iconic films it followed.
