In a movie, the man finally threw a dagger with snake venom and killed the bad guy.

Rat gall Rowen? Jet Li, Jacky Cheung, Oh Mom, Chingmy Yau, and blasting expert Li Jie (Jet Li) have all witnessed their wives and children being beaten to death and resigned from public office heartbroken because of their misjudgment in performing official duties. In the search for the killers of his wife and children, he used a bold pseudonym, worked as a bodyguard and body double for Emperor Rowen (Jacky Cheung), and performed desperate scenes for him from time to time. There is no clue except remembering the murderer's voice. TV host Le Hui Zhen (Chingmy Yau) suspects Rowen's performance, so she follows him day and night. Rowen was invited to attend a large jewelry exhibition. The gangster who calls himself a doctor (kelvin wong) plans to steal the diamond ornaments from the exhibition, and sends his assistant Zhu Fei (Zhou Jialing) to do public relations and undercover work in the hotel. On the day of the diamond show, Li Jie escorted Rowen to the scene and left. On the way home, he overheard the doctor's voice in the car, so he went back to chase the gangsters in desperation and staged a life-and-death scuffle.
