Female lead Feng Xiaoxue has just bought a house. Neighbor Liu Chunyan, holding a grudge for failing to snap up this house, repeatedly and maliciously harasses her in the middle of the night by falsely claiming she forgot her access card. Despite Xiaoxue's multiple acts of forbearance and calling the police, the other party escalates their behavior, even conspiring with her husband Gao Jianming—a corporate legal counsel—to spread rumors online, forcing Xiaoxue to sell the house at a 30 percent discount. Xiaoxue calmly collects a full set of evidence, seizes the opponent's weak spots, and submits the evidence at their promotion review meeting. The couple is sentenced for picking quarrels and provoking trouble, and Xiaoxue's family begins a new life.
