There are many shadows in the foggy city, and strange murders occur one after another: corpses folded into flowers, victims sewn into sculptures, twin murderers hidden in ten years of unsolved cases...
The captain of the crime team, Lu Heng, is skilled in both fighting and reasoning, breaking through the fog with thunderous means; Su Zhiyu, a newly promoted forensic doctor, is top-notch in anatomy and psychological profiling, and can read people's hearts from corpses.
When the two first became partners, they encountered the Iris Crescent serial case that spanned ten years. Later, they were involved in multiple high-IQ perverted art murder cases. The murderer used corpses as canvas and flesh and blood as paint, leaving bloody feasts in the city.
Every case is a carefully laid trap, and every reversal subverts cognition. They not only have to fight against the perverted killer hiding in the dark, but also face the abyss of human nature behind the case, and use the law and the truth to seek justice for every silent corpse.
Purpose: to expose the abyss of human nature, protect justice with the law, show the perseverance and warmth of criminal investigation work, and explore the boundary between sin and redemption.
