Psychological profiler Lin Shen was imprisoned for a well-documented murder three years ago and was ruined. On the night he was released from prison on parole, a new case imitating his "criminal tactics" occurred. The person in charge of the case was Shen Zhui, the female police detective who believed he was guilty and personally sent him to prison. Shen Zhui had to forcibly tie up Lin Shen, the "number one suspect" and "criminal consultant" in the name of supervision.
