Seven years ago, the "Jade Seal Case" broke out. Shen Mo, the son of a prison official in Gyeonggi Province, was devastated. He was wronged and exiled to the frontier.
Seven years later, he returned from his crime and became the chief of the "Crime Department", the most special yamen in the capital. He looks carefree and unruly, but in fact he has an exquisite heart that sees every detail.
Returning to the imperial capital, what awaits him is not only the change of things and people, but also a series of strange and bizarre unsolved cases:
The ghost bride evaporated out of thin air in the sedan chair, one hundred thousand taels of official silver disappeared from the treasury, and students from Taixue Academy were poisoned one after another... Behind every case, there seemed to be a pair of invisible hands, leading him to touch the tip of the iceberg of the unjust case seven years ago.
The person who was forced to partner with him was Lin Qingxue, the daughter of the imperial physician Ling and the chief widow of the capital. Childhood sweethearts in the past, now bitter colleagues. She was as cold as ice because of her love and resentment because of his "leaving without saying goodbye" back then. The two were tit-for-tat on official matters, but they had to hand their backs to each other at a critical moment of life and death.
Zhao Wuya, the commander of the Imperial City Division, appears to be both friend and foe, and has helped many times, but he always seems to have another side hidden...
