In the 1990s, sailor Lu Haisheng sailed all year round, handing over his entire salary to his mother Jiang Xiulan for safekeeping. Partial to her younger son, the mother misappropriated the elder son's money to invest in property for him. When a sudden emergency struck—his daughter-in-law Fang Qiaoyun experienced a difficult labor and his grandson was in a car accident requiring urgent medical treatment—Lu Haisheng returned home only to find his savings had been misappropriated without authorization. No longer blindly filial, he picked up legal weapons to sort out accounts, expose issues like forged guarantees, and protect his wife and child. After weathering storms, he recognized the root of family conflicts, assumed the responsibilities of a father and husband, repaired family relations, and steadfastly protected his family.
