He Qiyue was born into a family of widowers. Because her father was framed and died unjustly, she applied for the female criminal department in order to clear her innocence. The first case he encountered when he joined the company was the "Fake Death Case of a Miss from the General's Mansion". The deceased appeared to have died of illness, but He Qiyue discovered from the special pollen between her fingernails and half a secret message hidden in her hair that it was murder. During the investigation, Cen Yan, the young minister of Dali Temple, despised the woman's handling of the case and repeatedly set up obstacles. However, he gradually changed his mind after He Qiyue overturned his conclusion with the "details of the body". The two teamed up to investigate and found that the deceased and the victims of many previous "accidental homicides" were all related to an "arms theft case" ten years ago. As the clues deepened, He Qiyue discovered that his father's death was also involved, and the man behind the scenes was actually a high-ranking Duke of the DPRK. Faced with the threat of power and the betrayal of colleagues, He Qiyue used the "corpse" as evidence to uncover the truth step by step, not only to clear her father's wrongdoing, but also to allow the female criminal to gain a firm foothold in the court.
