Gu Zhaobai is the sharpest knife in the law firm, cold-blooded and efficient, and never accepts settlement; Shen Zhiyao is a former assistant who was sent to prison by her own hands, but returned three years later with a secret and a piece of evidence that can destroy the entire industry. When Shen Zhiyao tore up the settlement letter in public in the court, paper scraps flew like snow, and the whole court was in an uproar. Gu Zhaobai's fingertips trembled slightly, but he did not speak to stop it - she had known that this woman's return was not to beg for mercy, but to settle the matter. A revenge with the edge of the law started from a silent confrontation. No one knew that behind the "wrong judgment" that year was the life that Gu Zhaobai took for her.
