In the hidden corner of Mancheng, the greedy drug cartel uses all means to cause countless people to fall into the abyss due to drug addiction and their families are broken. Zhang Yao (played by Nick Cheung), who was persecuted by drug dealers to the point of family destruction, secretly cooperates with the anti-drug captain An Du (played by Ethan Ruan) for revenge. The two join forces to set up a game and ruthlessly eliminate the harm, vowing to completely eradicate the top two brothers of the criminal group, Mu Kun and An Pei.

In this contest, who is the chess player and who is the chess piece being manipulated? When the crisis comes quietly, it is better to sink or wake up. Be careful...
