Shen Qingci, the legitimate daughter of a legal family, fell into disrepair when her father was framed and died. She disguised herself as a man and disguised herself as "Mr. Shen" to write petitions for the public and settle trivial matters, hiding her ambition to overturn the case. Gu Yanzhi, the young minister of Dali Temple, is selfless but has a righteous heart. He secretly investigates the Prime Minister's party who framed Zhongliang, and unexpectedly meets Shen Qingci for the first time because of the "Embroiderer Suicide Case".
From the forced cooperation in the case of missing food for disaster relief in the south of the Yangtze River, to the case of Li Song's collusion with the enemy in the capital, which brought out Shen's father's old grievances, the two went from testing each other to frank trust.
Shen Qingci was awarded the title of "Female Recruitment Officer" for her talent, and Gu Yanzhi also regained control of Dali Temple. The two went from being allies fighting side by side to becoming lifelong partners, protecting their home and country with the law, and warming the years with deep love.
