The usually peaceful Chaoxi Dynasty suddenly became panicked, because everyone speculated that Princess Jinghe, who had been dead for twenty years, would come back to claim her soul, and the story unfolded...
As Su Yunxiu, an enthusiast of criminal psychology, traveled to the Chaoxi Dynasty, she naturally did not believe these soul-seeking remarks, so she firmly signed up to join the crime-solving brigade ordered by the emperor.
However, the leader of this brigade turned out to be Si Yebai, the second son who was unlearned and unskilled. Su Yunxiu couldn't bear the attraction of the case and had to compromise. In this way, this temporarily formed crime-solving team, whose faces and hearts are at odds, officially embarks on the road to find the truth.
As they get along day and night, the members of the crime-solving team appreciate each other's achievements and continue to solve various strange cases. However, they are surprised to find that the cases they have solved in the past are all related to an unsolved case twenty years ago...
