A report exposed that the renowned corporate giant JuLun Group in Canghai City has covered up the truth about a mining disaster that occurred years ago. Deputy Director Qu Jianghe (played by Pan Yueming) becomes the focal point of the anti-crime and anti-evil campaign. When he gets involved in the investigation, he realizes that the line between right and wrong in reality is no longer clear-cut. Due to various interests at stake, his opponents, friends, and even his superiors all demand the concealment of the truth. The newly appointed female director Yan Ge (played by Chen Shu) is also shocked by the harsh and heroic reality. Covering up is a greater evil than the crime itself.

Một tập báo cáo của JuLun Group nổi tiếng ở thành phố Thương Hải đã che đậy sự thật về vụ tai nạn hầm mỏ, khiến phó cục trưởng Khúc Giang Hà (do Phan Việt Minh thủ vai) trở thành tâm điểm trong cuộc chiến trừ gian diệt ác này. Cuốn vào cuộc điều tra, anh mới hay hóa ra cuộc chiến trắng đen vốn chẳng phân rõ hai màu đen trắng. Vì biết bao lợi ích mà đối thủ, bạn bè và thậm chí cả cấp trên của anh đều yêu cầu anh che đậy chân tướng thật sự, mà nữ cục trưởng mới được bổ nhiệm Nghiêm Cáp (do Trần Sổ thủ vai) lại không ngờ thực tế lại tàn khốc và hoành tráng đến vậy. Che đậy là tội ác còn nghiêm trọng hơn cả phạm tội.
