Law graduate Lin Xi and her grandma live in Feisha Residential Community. Wang Defa, the black-hearted property manager, neglects his duties, acts passively for a long time, and encroaches upon millions in public revenue of the community, while repeatedly threatening and intimidating the owners. Lin Xi collects complete evidence and organizes the owners to jointly report him. Multiple departments handle the case jointly, recovering the public revenue for the owners. The community establishes an owners' committee, carries out legal popularization and renovation, and returns to peace.
