Mo Li is an internationally renowned criminal psychology expert: cool-headed, incisive, and emotionally distant. Hired to assist the provincial police department with a series of ritualistic serial murders, she arrives at the first crime scene and comes face-to-face with her ex, criminal investigation captain Xing Muyuan, whom she has not seen in ten years.
Back then, she ended their relationship with a text message and vanished completely. Now, reunited, he acts all business on the surface, but secretly arranges for her to stay in the dorm room next door. He even keeps her photograph hidden in his study.
As the investigation deepens, Mo Li is shocked to discover that the victims and methods chosen by the killer perfectly match a case she studied at university. More frightening still, all the evidence points to someone who is supposedly dead: Wang Yunxuan, her mentor and former boyfriend.
When the seventh body is found, a taunting message at the scene points straight at Mo Li, and the task force begins to question her loyalties. Only Xing Muyuan stands by her, wagering his career to win her 48 hours to clear her name.
**On one side is the mentor she once loved, whose love has turned twisted; on the other is the ex who has waited for her without forgetting her for ten years.**
**As Zhou Mo's final trap is sprung, Mo Li must see through this killing game in the name of love before her psychological defenses collapse...**
