, Fan Shaohuang,,,, Xie Lixian, and Shao Yinyin Zhang (played by Shawn Yue) are policemen of the Secret Service (commonly known as "releasing snakes") guarding the deep water area. In this violent, bloody and sensual world, he has his own way of life. He often associates with gangs and has no goal in life. He is more like a young gangster than a policeman. Among the many *, he loves Lulu (Selixian) alone, which is not love or even pity, but when looking at Lulu, there is always a feeling of sleeping. On this day, Archie, the son of the gangster elder sister Chop Ma (), together with the rare emeralds smuggled into China by Archie, disappeared into the property of his sworn enemy Siyantang (). Mom knew that Zhang had contact with Siyantang and forced Zhang to come forward to negotiate with Tang, but Tang firmly denied that Archie had been arrested and the two sides were deadlocked. Mother Guo Zijian won the new director award for Moss, and even threatened to buy Siyantang. .......

Zhang is also in a dilemma. A killer (Fan Shaohuang) who looks like a street sweeper rushes into the Four Eyes Hall. Zhang Hutang hit the killer with a heavy punch, but accidentally killed Siyantang! The murderer became the only witness! Zhang Xin is afraid that after the police catch the murderer, the murderer will give up the truth of the murder by mistake. In order to protect himself, Zhang tried every means to catch up with the murderer before the police! In the process of being chased by Zhang, the killer met Lulu and knocked her unconscious, even threatening Lulu's cousin Ahua (stone ornaments) to escape! Zhang watched Lulu, who was in a coma, be sent to the intensive care unit, only to find that his feelings for Lulu were far deeper than he thought, and his anger was burning out of control between self-protection and hatred, and he was juggling with the pressure of gangs and police. A few low-ranking people, a deep-water dark war, the official curtain call! Whoever has the strongest vitality will be the final winner!
