Fifteen years of devotion, and Shen Qingyan's husband Gu Yunzhou repays her with a mistress—bringing his pregnant lover Liu Ruowei into their home. Liu mocks Shen's childlessness while trampling her deceased children's memorial tablets. Gu broke his vow to "never betray her even if it means no heirs," enabling his mistress and plotting against his wife. But Shen Qingyan is a general's daughter—she won't be humiliated. She methodically gathers evidence, forms alliances, and prepares a trap. Not only will she divorce this faithless man—she'll bring his entire family to ruin, making the betrayers pay.
