Gu Niansheng, a criminal psychologist in Haijin City, retired from campus three years ago because of the psychological trauma caused by an unsolved case. Until the serial murders reappeared and clues to the disappearance surfaced, she was forced to return to the front line and partnered with Lu Yanci, the criminal police captain with facial paralysis. Everyone said that Lu Yanci was cold-blooded and ruthless, but he pressed on her every step of the way - "Gu Niansheng, do you think you can escape?" The murderer imitated the method of committing the crime seven years ago, and every corpse pointed at her. When the truth was revealed, she discovered that the most dangerous hunter was always around. The yandere professor x the facially paralyzed captain join forces and use the heart as bait to break the deadlock.
