Lin Wan, a trainee nurse in the emergency department, exposed in public that the attending physician Jiang Yan had falsified medical records, causing an uproar in the hospital. Unexpectedly, Jiang Yan refused to argue or get angry, and only played a video of a battlefield rescue from three years ago - the person he desperately saved in the video was actually Lu Ming, who now controls the lifeblood of the hospital. Lin Wan accidentally discovered that this forgery case was just the tip of the iceberg. The two were forced to form an alliance. With the secret assistance of forensic doctor Su Tang and the silent cover of security guard Zhou Xiao, they uncovered a huge conspiracy intertwined between pharmaceutical companies, management and medical shady circles. The person who really deserves to be judged is never a certain doctor, but the entire system that suffocates the truth.
