She was expelled from the police force and became the object of reviled by the entire Internet. Three years later, while working anonymously at the bottom, she was accidentally involved in a serial murder case that was highly similar to an old case from that year. In order to find out the truth and clear his grievances, Lin Mo returned to the public eye despite the pressure of public opinion. He used his amazing criminal profiling ability and sensitivity to details to step by step in the game between the police and the murderer. In the process, she intersects with the seemingly cold and distant mysterious entrepreneur Lu Chenyuan, who always seems to hold key information in the dark. The two go from testing each other to fighting side by side, and gradually uncover the huge interest group hidden behind the case - and all of this is closely related to the black hand that destroyed her life three years ago.
