Mo Li is an internationally renowned criminal psychology expert who is calm, sharp and inhumane. She was hired to assist the provincial department in investigating a series of serial murders with a strong sense of ritual. However, at the scene of the first crime, she met her predecessor, the criminal investigation captain Xing Muyuan, whom she had not seen for ten years.
Back then, she ended the relationship with a text message and disappeared completely; now that they were reunited, he seemed to be doing business, but secretly arranged her to stay in the dormitory next door, and there was still a photo of her hidden in the study.
As the case progressed, Mo Li was shocked to discover that the murderer's chosen victims and his methods matched perfectly with the cases she studied in college. What's even more frightening is that all the evidence points to a "dead" person - her mentor and ex-boyfriend Wang Yunxuan.
When the seventh corpse appeared and a provocative message directed at Mo Li was left at the scene, the task force began to doubt her position. Only Xing Muyuan stood by her side, risking his career to fight for 48 hours for her to clear herself from suspicion.
**On one side is the mentor she once loved deeply but was twisted, and on the other is her ex who has been waiting for her for ten years. **
**When Zhou Mo's final trap is activated, Mo Li must see through this killing game in the name of love before his psychological defense collapses...*
