After emergency department intern Zhou Ye was publicly humiliated by the director, he broke into the morgue alone at three in the morning and used his mobile phone to take photos of three wrongly identified corpses, causing an earthquake in the hospital. Lin Zhao, a cold-faced neurosurgery doctor, discovered that one of the corpses was actually the victim of an accident that he did not dare to reveal three years ago, while forensic doctor Su Rui discovered evidence of the family mentor's guilt in the autopsy data. Nursing worker Zhao Tiezhu silently provided the buried medical record fragments, while disciplinary inspection director Chen Suyun was encircling and suppressing the case step by step, trying to use procedural justice to obliterate the truth. When a hole is opened in the shady curtain of systemic corruption, Zhou Ye and Lin Zhao must use the corpses to reveal the truth of the medical malpractice that has been covered up layer by layer in the system's siege.
