I am a psychiatrist who specializes in "conscious submersion" therapy. I can enter the mental world of patients with multiple personality disorders (DID), talk to their different personalities, and provide integrated treatment. Until I took over a special patient - a vegetative person involved in seven unsolved cases. Police believe he was the only witness. When I entered the depths of his consciousness, I was shocked to find that this place was not a healing garden, but a "criminal museum" composed of countless distorted memories. Each of his personalities corresponds to a character in an unsolved case: the "child personality" is the victim of the first case, the "angry personality" is the murderer of the second case, and the "bystander personality" witnesses the third case... I must deal with, deal with and even confront these personalities in this dangerous mental maze, and piece together the truth of the seven unresolved cases from their chaotic narratives. But the most dangerous thing is that there is a "master personality" in this cage of consciousness that even the patient himself does not know. He is trying to trap me here forever and become a new collection of this museum.
