Xu Yahan gives birth to her daughter Niannian and is in postpartum confinement. Her son-obsessed mother-in-law, Xu Huifang, blindly believes the absurd theories of her eldest aunt, Xu Huilian, and uses folk remedies to force her to have a son. The eldest aunt is actually burdened with high-interest loans, impersonates a gold-medal maternity matron to scheme against the in-laws' family, and tricks the mother-in-law into drinking a toxic remedy, causing Zou Mingkai to fall into a coma while also bewitching the mother-in-law into selling off the real estate. Xu Yahan collects surveillance evidence, exposes the entire scam, and the fraudsters are arrested and sanctioned by the police. The mother-in-law wakes up to reality and repents, the husband thoroughly awakens and regrets, and the family resolves their estrangement, welcoming a harmonious and stable life.
