Criminal psychologist Lu Chen and forensic doctor Su Wan were involved in this, and they uncovered the bloody truth about the mysterious disappearance of the two people during a mountaineering trip ten years ago and the joint efforts of everyone to bury them. He admits that the murderer is just a pawn, and the real avenger has been dormant for ten years, plotting a shocking killing plan. When the frozen skeletons are revealed again, all sins will eventually be paid for with blood.
Purpose: This article uses the serial murder case of the closed villa as the shell, and uses the dual-line narrative of revenge and investigation to criticize the distorted justice of using violence to fight violence and lynching verdicts, revealing the evil of human nature caused by cowardice, greed and silence, and clarifying that the real salvation is not killing for revenge, but adhering to the rules, facing one's faults and keeping one's conscience.
