The son of Vice Mayor Nie Dahai, the chairman of Tiandu Longteng Group, and a famous young entrepreneur in the province, these are all titles given to Nie Mingyu (played by Chen Daoming). But his most important identity is the leader of the largest underground gang in Tiandu. Nie Mingyu, who is usually handsome and polite, is actually a hypocrite. He used his well-developed interpersonal network to bribe customs officials, smuggle goods, and make huge profits. And his right-hand men are also extraordinary and vicious. Under their management, Longteng Group's performance has risen step by step. But there is no wall that is impenetrable in the world. An anonymous letter of accusation was delivered to the Organization Department of the Provincial Party Committee. Nie Mingyu and Longteng Group's activities have aroused the high vigilance of the Provincial Party Committee, and ordered Tiandu City to quickly find out the cause. But Nie Mingyu's influence has already covered the entire Tiandu City. The Municipal Party Committee arranged Nie Mingyu's brother, the captain of the criminal police team Liu Zhenhan (played by Tao Zeru) to investigate the matter, in order to continue to cover up Nie Mingyu's crimes. A contest between family affection and justice unfolded on Liu Zhenhan. In the battle between good and evil, who will win?
