When their old family home is demolished, five apartments are allocated. But her biased parents give all the property to her cousins, Gao Qiang and Li Li, completely excluding their only daughter, Lin Wei. During an argument, she unexpectedly discovers that her and her son's household registrations are the key to the apartment allocation, and that her relatives were never eligible to receive any apartments in the first place. After years of being emotionally manipulated by her family, Lin Wei refuses to back down. She produces an itemized account of the twelve years she has devoted to them and calmly fights back with the power to approve the allocation. In the end, she exposes the fraud behind their supposed family debt of gratitude, protects the property that rightfully belongs to her, and breaks free from the unjust emotional ties binding her to her family.
