In the twenty-second year of Chengping, the Su family suddenly encounters a great disaster. Su Zhiyi returns to Yingtian Prefecture to save her imprisoned father, only to meet Lu Xian again in the prison—her former husband who abandoned her with his own hands three years ago. The once down-and-out youth has now become the Commander of the Northern Surveillance Bureau, holding power over the court, pressing her step by step, humiliating and possessing her. Meanwhile, she is already the "Madam Xie" who escaped from the general's mansion, with the crisis of Xie Lanci chasing after her still hidden behind her. To prop up the Su household and rescue her father, she picks up medical skills once more, maneuvering among Lu Xian, Zhao Shijie, the Grand Princess, and Ye Qingrou in the vortex of powerful nobles. Old scores of love and hatred, power calculations, and layers of false marriage contracts erupt one after another; she only wants to escape and leave the capital, but with reddened eyes, he refuses to let her go.
