In money and hatred, all employees are suspects. The plot turning point of this movie may be the highlight of the whole movie. At first, I thought that the murderer was, and later I suspected that it was Inspector Ye, and finally I realized that it was a gang for revenge. Good people become bad people, and bad people are pitied because of greed that does not belong to them. Because police officer Ye failed to catch the leader of the robbers and was even hit once, he hated these robbers, so he arranged undercover. As a result, the undercover was exposed at the crime scene and then killed. In order to avenge his buddies, he actually chose Jianghu means to fight violence with violence, incite the families of the victims to join, provide them with information, let them take revenge, and find an excuse to kill others to stay out of it.

In the process of chasing the gang of robbers, the man analyzed that if Louis Koo had got the jewels, he would have escaped long ago. Since he is still here, it means that he didn't kill his partner and didn't get the jewelry, which also confirms his previous inference. Even in the face-to-face confrontation with the man, he pointed out that Mr. Ye was the most suspected murderer. The man was about to raise doubts about Sir Yip to the police, only to find that he had been dumped on the coast. It can be said that the murderer was several people.

The clue was temporarily interrupted, and the man had to re-investigate the three suspects he suspected. He found that the pork seller was making explosives in a secret place, and the cashier's woman was carrying the same jewelry that was lost in the robbery. Everything is finally connected. The pork seller, the cashier, the security guard and Sir Ye are all accomplices, and they all have the motive to kill. It was this criminal gang that divided the spoils unevenly, and the infighting killed Sir Ye. The man immediately rushed to arrest the security man after confirming the case, but it was too late. There was a gun battle between Louis Koo and the security guard, and both of them were killed.

The final result is that under the continuous investigation of police officer Lin Faliang, the murder of the robber Xu Bulan finally came to light. In order to avenge his paralyzed girlfriend, He Zhaodong, the former jewelry guard, killed Xu Bran and took the jewelry, and then framed the gangster Wang Xinyuan. Ye Shouzheng, an inspector who knew this matter and participated in the stolen goods sharing, always believed that Wang Xinyuan was the murderer who tried to shield his accomplices and prevent Lin Faliang from investigating them, but was later killed by He Zhaodong and Yao Sheng because of the stolen goods sharing.
