Zhou Shengnan, a retired long-haul truck driver, uses her hard-earned savings to buy a health-monitoring smartwatch, only for her husband, Luo Jianmin, to smash it and kick her out of their home. She temporarily moves into a freight station, reports her salary card lost, cuts off her daughter's mortgage payments and her husband's supplementary credit card, and gathers evidence to defend her legal rights. With the support of her daughter, son-in-law, granddaughter, and fellow workers, she gets divorced, recovers her assets through legal means, and eventually regains her property, beginning an independent and peaceful retirement.
