The story of Gun King begins with a real shooting competition. GuanYouBo, the foreign exchange investment manager played by Louis Koo, left with a gun after winning the game, but he happened to be robbed on the way. In order to save a traffic policeman, GuanYouBo shot to stop the robbers from killing the policeman.

This righteous act made him a hero in the eyes of the citizens. However, Zhuang Weizi (Daniel Wu), a defeated officer, is also investigating the case, only to find something else. He has all kinds of entanglements in his heart, from doubt to belief. Finally, with the help of Brother Miao (Fang Zhongxin), the fog is solved.

The shooting scene with gangsters at the beginning of the film can be understood as the scene where my testimony was restored after I was taken away by the police, because the witnesses at that time were only about Youbo, which is why Zhuang, who plays it, is suspicious. However, due to the lack of physical evidence, we can simply sue GuanYouBo for illegally using guns.

Before the jury reached a verdict, GuanYouBo's "heroic" deeds were widely publicized by the media, and Shao Anna's behind-the-scenes help was finally acquitted.

However, some detailed stones will once again break the surface of the calm case. First, the fugitives have not been captured. Secondly, GuanYouBo is nervous about foreign exchange trading. At this time, I'm afraid only friends sitting near the screen can see the real content of GuanYouBo's screen. He used his earned foreign exchange to make up for Shao Anna's loss of foreign exchange. At this time, I recalled the words of Miao police officer played by Fang Zhongxin, "Those rich people are rich, why don't they retire?" .

When GuanYouBo was attacked by escaped robbers, the truth began to surface, and GuanYouBo took out bearer securities from his sports car. Later, at the gun meeting, his relationship with the jailbreak robbers broke out. However, because there is no physical evidence of any witness, no measures can be taken against him. With your help, Zhuang designed a game to let Tingting tell him that "the traffic police will wake up". Sure enough, GuanYouBo was assassinated at night.

Unwilling to fail, he decided to make a final attempt, but his idea had been mastered by Zhuang. After the failure, I decided to compete with Zhuang. Two people fired almost at the same time, but the picture showed that GuanYouBo was faster. Zhuang punched Guan's left hand and knocked off his gun. Guan's bullet hit Zhuang's chest Protected by bulletproof vests, Zhuang escaped. At the last minute, Guan tried to pick up the pistol again, but was killed by the twin brother of the traffic police who was lying in ambush.

Through the final duel, we can see that the real gun king is Zhuang, because he aimed at the opponent's hand, not the fatal part. The highest level of using a gun is not killing people, but saving people.
