A bizarre secret room murder case forced the unknown criminal investigation captain Jiang Chushi and criminal psychology expert Qian Zhiyu to form a partnership. The victim's strange death posture and the clues deliberately arranged at the scene all imply that this is no ordinary murder.

When their reasoning was overturned again and again, they had to face a terrible fact: behind these cases, there seemed to be an invisible hand controlling every step of their investigation?
