Shen Gui, once a forensic doctor, has now become the only member of the "Gui Ling Office". What he investigates is not ordinary supernatural events, but those "out-of-control realities" that are covered up by the authorities - when the boundaries of common sense are torn apart, time goes back, memory is confused, and the dead are resurrected, the entire city seems to be controlled by invisible hands. Shen Gui's motivation is not justice, but to find his sister who has been missing for many years. She is the first batch of "out of control" victims. Each case is like a puzzle piece, uncovering the huge experimental conspiracy behind it. As the investigation deepened, Shen Gui discovered that he was also a pawn on the chessboard, and his true identity was confusing. In a city full of puzzles, distorted reality and family obsession, Shen Gui must make a choice between the truth and himself. Do you dare to spy on this forgotten truth with him?
