Recently, the Binhai City Anti-drug Brigade received a report of drug trafficking, and the detachment leader Qi Weibin led a team of 6 people to investigate. The originally smooth tracking process suddenly had problems, and Qi Weibin had to take the risk alone to break into the drug den. Later, after his teammates came to support him, he wiped out the drug den. However, the main criminals, the Duan brothers, still escaped, and then retaliated, killing Yan Kang, the leader of another group of drug dealers who had been under police surveillance for many days, and the anti-drug team lost an important clue. The police cooperated with multiple police forces and found clues during the investigation of the murder case. They determined that the suspects were the escaped Duan brothers. Through the investigation and the sorting out of relevant clues, they analyzed the cause and effect of the incident and determined that there was a mastermind behind the scenes. As a result, "Loach", who had been engaged in brokerage work for a long time, came into the sight of the police. The cunning and suspicious middleman "Loach" was arrested in the roundup designed by the police, and finally confessed the true identity of the online behind the scenes. At this point, several cases that were related to each other were thoroughly sorted out, and several important suspects surfaced. The Binhai City Bureau launched a comprehensive cleanup operation, codenamed "Rage". The Binhai City Bureau struck with lightning speed and strictly cleaned up the system, and finally completely removed the two tumors that had been lurking for many days, returning a bright and sunny day to Binhai City!
