Su Jin, the goddess of the neurosurgery department at Jiren Hospital, Qin Che, a powerhouse in cardiac surgery, and three other elite doctors are not only close friends but also workaholics. During an ordinary night shift, they unexpectedly intercept a strange bioelectric signal from inside the hospital. After decoding it, they discover it points to a bizarre death perfectly disguised as a medical accident. From then on, the familiar hospital becomes a maze, trusted colleagues may be wearing masks, and behind the advanced medical equipment lurk chilling alternative uses. The five are forced to become "hospital detectives," using their professional expertise to solve mysteries, only to discover they have already stepped into a vast maelstrom involving cutting-edge biotechnology, the black-market organ trade, consciousness transfer, and even more horrifying fields. As they save lives, they must also lift the "veil of sinister secrets" shrouding the hospital and face an unseen opponent in an ultimate battle over life, ethics, and truth.
