During a business trip, Zhou Lan hired a live-in caregiver to look after her father. Upon returning, however, she discovered that the door lock password had been altered, and the caregiver Wu Xiulian had actually brought her entire family to move into her school district apartment without authorization. Her father was placed on a folding bed in the study, running a high fever and severely ill with no one to care for him. Armed with complete evidence and facing their repeated difficulties—such as stealing valuable property from the home and malicious cyberbullying—Zhou Lan refused to compromise, pursuing the full responsibility of both the caregiver and the derelict housekeeping company through legal means to safeguard the bottom line of her family and the law.
