A report from the famous enterprise Julun Group in Canghai City covered up the truth of the mining accident that year, making Deputy Director Qu Jianghe the focal point of this campaign to crack down on crime and eliminate evil. When he intervened in the investigation, he found that there was no clear boundary between black and white in reality. Out of various interests, his opponents, friends, and even his superiors demanded to cover up the truth of the facts. And the newly appointed female director, Yan Ge, did not expect the reality to be so cruel and heroic. Covering up is a greater evil than the evil itself.
