Tsui Hark takes the reigns of this series following a much-publicized rift between himself and John Woo -- the director of the first two A Better Tomorrow films -- to direct this prequel based around Chow Yun-Fat's memorable Mark character. Set in 1974, Mark ventures to Saigon after his cousin, Cheung Chi-mun (Tony Leung Kar-fai), gets into hot water with the local police. Using a contact in the Vietnamese army, the two soon start trafficking black market weapons with a beautiful female assassin named Chow Ying-kit (Anita Mui). After a deal goes horribly wrong, the three -- along with Ying-kit's father -- try to leave Vietnam, only to have Ying-kit be detained by customs. Back in Hong Kong, Mark and Chi-mun set up a small garage. When Ying-kit returns, her old mobster boyfriend, Ho (Saburo Tokito), also makes an unwelcome appearance. Though Ying-kit has fallen for Mark, he refuses to reciprocate because Chi-mun has fallen for her. Ho hates them both and tries to kill them with a well-placed bomb. Though the attempt fails, Ho promises more if the two don't leave town. Instead, Ho leaves for Saigon with Ying-kit who is quietly plotting revenge. Mark and Chi-mun soon follow them, hoping to save Ying-kit and kill Ho themselves.
