As soon as Ling Mo's scalpel opened the chest of the seventeenth unknown deceased, detective Lu Chen came to the door with a strange murder case. The dead man's palm was engraved with the mark of a crossed scalpel, and the shape of the fatal wound was surprisingly consistent with the old scar left by Ling Mo many years ago.
A series of murder cases followed, and each victim had scars that imitated the old cases. All clues vaguely pointed to this female forensic doctor who was known for her calmness. Lu Chen struggled between trust and suspicion, while Ling Mo was forced to tear apart the dusty memory - the "scalpel murder case" in which she almost died that year. The real murderer may have never been caught.
When the seventeenth wound quietly appeared on Ling Mo's arm, the skin tissue between the deceased's fingernails completely matched hers. Is it the murderer's malicious intention, or is her suppressed dark personality out of control? In the flash of the scalpel's cold light, the truth is hidden in the deepest abyss of human nature, and they have become the prey of a hunting game.
