On a rainy night, a corpse with a white platycodon stuck in its chest dragged Lin Shen, a former criminal investigation genius who had retired for three years, into the abyss again.
The deceased was a wealthy man in Jiangcheng, and the next body appeared one after another, with the same flowers, the same way of death, and the same hatred - platycodon as the contract, and killing as the sequence.
The murderer accurately provoked the police, named Lin Shen, and regarded himself as the judge to settle a betrayal and blood debt that had been buried for twenty years.
The unsolved case back then was unsolved, but now the evil shadow has reappeared. Lin Shen and policewoman Su Wan teamed up to pursue the murderer, and uncover the truth amid lies, interests and old wounds.
What he is looking for is not just a serial killer, but also the darkness he escaped from back then, and the justice that was twenty years late.
Every flower declares: the game begins, sinners must die
