In the winter of 1978, sixteen-year-old Chen Yanqing bludgeons a powerful man’s son to death and flees into the snowy night. He does not rely on brutality, but makes “rules” his foundation: no drugs, no harming women or children, debts repaid within three days, and traitors lose a finger and are cast out. From hauling cargo at the docks to controlling Heyang’s underworld, he reshapes the jianghu with contracts, yet at the height of his power, he lets down everyone he loves. As the tide of the times sweeps in, this “godfather of the street gangs” who lives by the rules finally finds redemption amid blood and snow.
