Guan Jingtang, a well-known local elderly man, died tragically in his villa.An Ping, the criminal police captain, was ordered to do so in the face of danger. Shang Jie, a top student in the provincial department, took the initiative to ask for help. The two cooperated fully and launched a meticulous investigation.

However, as the investigation continues to deepen, various self-contradictory doubts emerge one after another. Coupled with the huge amount of missing cash, the familiar woman in red, the flower pattern as red as blood, and the complicated interpersonal relationships of the Guan family, the case...More and more confusing.

Not only that, murders are still happening one after another, and the deceased have a close relationship with Guan Jingtang.Anping and Shang Jie withstood huge pressure, investigated from the source, and uncovered an old case. Anping's master, who was also Shang Jie's father, died because of that case.

Finally, Anping peeled off the cocoon, solved the unresolved case, uncovered the real culprit behind the scenes whose psychology had been distorted, and brought him to justice.Shang Jie also came out of the haze, untied the knot that had troubled her for many years, and determined to inherit her father's legacy and fight side by side with Anping.
