Zhou Yu'an, a renowned law firm founder who graduated from the law school of Tsinghua University, returns to his hometown and discovers that Zhang Jianguo, the neighborhood committee director, has been occupying his family's privately owned parking space for three months. When his parents try to defend their rights, Zhang Jianguo and property manager Huang Youde join forces to bully them. Armed with his professional legal expertise, Zhou Yu'an launches a fierce counterattack. When his opponents resort to locking his car, splashing paint on it, and slashing its tires, he responds to every malicious act with a legal solution. Not only does he successfully reclaim the parking space, but he also exposes the two men's illegal scheme of renting out parking spaces for profit. In the end, Zhang Jianguo loses the lawsuit, faces enormous compensation claims, and is abandoned by everyone around him. The property management company makes rectifications and apologizes, while Zhou's father wins a landslide victory in the election for the new neighborhood committee director. Through a comprehensive legal battle, Zhou Yu'an secures justice for his parents and restores order to the community.
