In the "Floating City" of the southern industrial city in the 1990s, sin and opportunity were entangled in steam and neon. Chen Xiao, a young man from a shantytown, struggled like a weed under the fists of his alcoholic father. After dropping out of school, he fell into a quagmire of theft and brawls. In a street melee, he rescued Zhou Yongqiang, a gangster, and stepped into the world of swords and swords. From a low-level boy to a "big man" who controls gray industries such as entertainment and logistics, he used ruthlessness and agility to build an underground empire. However, at the peak of his power, he was surrounded by the wave of the rule of law, internal divisions and the criminal police Zhao Zhigang's legal network. When he stood in the dock and looked back, the bloody journey stretched from the dilapidated shanty to the prison, and he realized that the gears of fate had already carved a footnote for Brother Qiang's destruction the moment he rescued him. This is an elegy about the wild growth of weeds, the corruption of power and the strangling of the times.
