Independent startup founder Su Qingyan hires nanny Wang Guilan, who repeatedly meddles in her life, interferes with her consumption, and secretly brings her son Zhao Qiang to her home for a blind date. Taking advantage of Su Qing's absence, Wang Gui and a group of relatives break into the home to eat and drink, destroy collectibles, and kill pets, and Zhao even beats and injures Su Qing. Su preserves the surveillance footage and calls the police, Zhao is sentenced on multiple charges, and Wang Guilan is jointly and severally liable for debts, becoming a discredited person relying on scavenging to survive, reaping what she has sown.
