In 1998, thick fog locked the river at Linjiang Wharf. Lin Mo, a criminal investigation genius from the police academy, was about to graduate. He was framed by the evil forces and was expelled due to the criminal record. His life fell from the clouds into the quagmire. His mother was in an advanced stage of uremia and urgently needed life-saving money. Local gangsters were pressing closer and closer. Jiang Yi, his former brother, became a criminal police officer on the opposite side. Desperate, he plunged into the dock where dragons and snakes were mixed, and started from the bottom as a cargo carrier.
He set the iron rule of "don't touch drugs, don't kill people, don't bully the weak", and teamed up with the orphans of the Shen family to fight against the evil forces and transnational drug trafficking networks that dominated Hong Kong City in the gap between light and darkness. The tide of the river is surging, and it is difficult to distinguish between good and evil. No one knows where this dangerous road of being involved in the situation will eventually lead.
