Synopsis

Four years after the Jianzhou Tunnel collapse, a contractor livestreams his suicide and blows the whistle under his real name on corruption in public bidding. The disciplinary inspection commission sets up a special task force headed by Ren Gengqing. His target is his former classmate Du Qingbo, allegedly involved in bid rigging and collusive bidding. Against resistance from many sides, the task force takes down the whole corruption network in the bidding sector, protecting fairness and justice in the business environment.
