Xia Chunsheng is retiring from the anti-drug team next week. He wants to go to Sister Hua's restaurant for a meal with Cui Tiejun, the big stick Xu Guozhu and the big troll Pan Jianghai, who were known as the four famous arrests in the past, and mediate with Cui.There was a conflict between Tie Jun and Xu Guozhu, but the three of them didn't take issue with each other. Xia Chunsheng was quite helpless. He told the three of them that they must be present at the wine party he ordered, otherwise they would not recognize him as his eldest brother.The anti-drug team received reports from the public that several drug dealers were conducting drug transactions in a hotel in the suburbs.The captain of the anti-narcotics team, Lao Tian, led the team to prepare for an arrest, but Xiao Lu, a young police officer who had just graduated from school, suffered from diarrhea.Xia Chunsheng, who had been transferred to the back office, volunteered to take part in the operation in place of Xiao Lu. However, he never expected that something happened and Xia Chunsheng died.
