Shen Zhiwei was expelled from her husband's family and when she knelt down to beg for her return, she set the old house on fire. In the firelight, she saw Huo Yanchuan's hypocrisy, the old lady's viciousness, Su Xingtang's forbearance and Lin Rushuang's calculations. No one knew that the fire not only burned down the old house, but also burned away her last trace of tenderness. When the government came to investigate, she handed over a blood-stained account book - which contained evidence of the crimes of three generations of the Huo family, as well as a secret letter about her life experience left by her biological mother.
