There is an undercurrent in Yonglan City, and an underground drug network that has been entrenched for many years is crisscrossing and spreading.
Lu Song, the backbone of the criminal investigation who is restrained and calm and obsessed with old cases, meets Xie Zhe, a free and sharp detective who dares to break out and fight hard. The two formed a temporary team, starting from a small clue, to hunt down the evil behind layers of fog.
The Xicang stronghold collapsed, the mountain was empty and the rainy night was laid out, and the Xincang closed the net in the dark night. They removed the bottom chess pieces layer by layer and captured Lin Baisu, the chess player in front of the stage. Everyone thought that the big case was settled, but only Lu Song and Xie Zhe realized that the person who was arrested was just a carefully prepared cover-up.
The person behind the scenes, codenamed Spades K, has always been hiding in the void, without showing any trace, waiting for the chess game to restart.
The shadow of the gun accompanies the night, and the wind and rain chase the murderer together.
Countless life-and-death encounters, and tense investigations aside, fireworks quietly breed affectionate feelings every day.
They travel through the boundless darkness, face the treacherous nature of people's hearts and numerous traps, using the police badge as their blades and each other as their backs.
Even though the mist lies across, the abyss lies ahead;
Just walk side by side, overcome thorns and thorns, and wait for the dawn to break.
Purpose: Fight against evil with courage, the darkness will eventually dissipate, and the dawn will eventually come.
