Psychiatrist Lin Chen has always believed that so-called "supernatural phenomena" are nothing more than mental foci of the collective subconscious of mankind. Until he was forced to take over a series of extremely weird cases: a business executive who believed that his shadow was whispering, a painter who claimed to be able to see the "real texture of the world" but kept mutilating himself, a girl whose body gradually became "transparent" and disappeared... The only way to cure them was to venture into their twisted and crazy "mental world" and destroy those "cognitive abnormalities" nourished by fear.
However, every time the "treatment" was successful, Lin Chen began to experience strange things: inexplicable whispers in his ears, strange symbols flashing in front of his eyes, and the "Inhuman Contract" that inexplicably appeared on his desk, recording all unknown taboo knowledge. He gradually realized that he was not "healing", but was acting as an agent for some higher existence to "harvest" fear. Every "infiltration" was an attack on the barriers of reality, introducing more "pollution" into reality.
He is the only one who can "see" and "fix" the cracks, but he is also the culprit who keeps creating them. When the fears of former patients manifest themselves into man-eating monsters in the city one by one, and when a global "cognitive disaster" begins to erupt, Lin Chen must find the narrow road between madness and reason, destruction and salvation before he is completely assimilated into an inhuman existence. The world is sick, and the medicine may be more deadly than the disease itself.
