A car accident in broad daylight is a small prologue to this masterpiece of mystery.
The policewoman Pei Zhiyi is calm and capable, and is an elite in the police station; the newcomer Chi Qinghe is passionate and delicate, and has beast-like intuition. The partners, one cold and one hot, were ordered to investigate the case, but they tore the tip of the iceberg of a huge black industry chain from the rotten stench near the scene of the car accident.
However, the direction of the case is far beyond everyone's imagination. The sudden appearance of human fat in the gutter oil is like a huge boulder thrown into stagnant water. Under the ripples, old murder cases that have been dormant for many years, suspicions of cannibalism that challenge the bottom line of human nature, and a cruel school bullying case that has been forgotten by time have surfaced one after another.
Pei Zhiyi and Chi Qinghe, one is like the cold moonlight of rationality, and the other is like the original fire of emotional warmth. They formed an excellent complement to each other as they walked against the light and pursued the truth. Chi Qinghe can always see the details that Pei Zhiyi ignores, and Pei Zhiyi can find a rational fulcrum for Chi Qinghe's intuition. They are each other's eyes in the dark and the most reliable back in a hail of bullets.
When all the clues mysteriously return to the starting point, they must uncover the saddest truth and the most desperate revenge behind the car accident.
This is an intellectual race against a perfect criminal, and it is also a duet of hope played in the darkness of human nature.
