Description：After months of fighting over casino interests, the two major Macau gangs, the Hung Hing Gang and the Yee Ying Gang, decided to make peace. However, word spread in the underworld that the leader of the Hung Hing Gang, Broken Tooth Wah, had hired an outside killer for five million yuan and was preparing to assassinate the eldest brother of the Yee Ying Gang, Gao Lao Zhong. In order to ensure Gao Lao Zhong's safety and prevent chaos again, Broken Tooth Wah sent his capable subordinate, Achen (Tony Leung), who is also a corrupt policeman, to stop it from happening. The bald killer Yaodong (Lau Ching-wan) and the mysterious woman Afeng (Maggie Shiu) often haunt Achen and constantly cause trouble for him. It turned out that Yaodong was a super killer sent by Mr. Hung, the boss behind the gang, to smash the Hung Hing Gang and the Yee Ying Gang. His killing methods were very sophisticated and ruthless. After some arrangements, Yaodong created a situation where Broken Tooth Wah and Gao Lao Zhong both died at the hands of Achen, but his fate was not controlled by him.
