Description:Ren Yinjiu, a gangster who has been acting exaggeratedly and unscrupulously in the world for twenty years, has made countless enemies. One of his undercover agents in the police, Ye Weixin, learns during an investigation that someone is going to kill Ren Yinjiu. When Ye Weixin tells Ren Yinjiu that, Ren Yinjiu shakes his head and waves his hands, thinking that is just a boring joke. When he is getting a haircut, a bullet flows from a dark place and scorches his hair. At that time, Ren Yinjiu finally believes that someone really wants to take his life and he convenes a meeting immediately. After Ye Weixin takes over the investigation, he reminds Ren Yinjiu to list the suspects according to Gu Long's famous sentence, "The biggest enemy is always a friend by your side". As a result, the first one that appears in Ren Yinjiu's mind is his wife, Su Hua.
