A new work is here. At a private hospital, a string of strange deaths among postoperative patients has occurred. Every case points to a new painkiller called “Amber.” While investigating, emergency physician Lu Shen discovers that every victim signed a “Do Not Resuscitate Consent Form” while conscious, yet autopsies reveal drug residues far above the safe threshold. As the investigation deepens, he gradually uncovers a conspiracy between the hospital's senior executives and a multinational pharmaceutical group. But he has no idea that he has already fallen into an intricately designed scheme within a scheme. From vanished electronic medical records and mysteriously missing physical evidence to victims of memory-reconstruction experiments and a psychiatry department head with the power of hypnosis, everyone is playing multiple roles.
