Shen Yan, a teacher who newly moved into Huaqing Garden, faced malicious harassment from neighbor Zhou Lifen due to buying a car. The other party repeatedly harassed him late at night, and even teamed up with her husband, who is a legal professional, to create cyberbullying, forcing Shen Yan to sell the car at a low price. After property management mediation failed and his work suffered a heavy blow, Shen Yan gathered complete evidence to launch a desperate counterattack, expose the other party's conspiracy, protect his family, and prove that evidence and rules are the true foundation of ordinary people.
