When elderly fisherman Chen Guozhu suddenly learns that his older brother overseas has passed away, leaving him an inheritance of 30 million yuan, he decides to keep the news secret. Pretending that he and his wife are poor and ill, they put on old clothes and travel to the city to borrow money from their three children, testing their filial devotion. His biological son and daughter-in-law look down on them and make excuses, refusing to lend them a single cent. His biological daughter dismisses them with just 200 yuan. But his adopted daughter, Xiaonuan, offers the only 3,000 yuan she has saved. Deeply moved, Chen gives her the entire inheritance. His biological children then spread false rumors about him through livestreams. At a mediation session, Chen plays a recording that reveals the truth. In the end, Xiaonuan opens a new restaurant, and the whole family reunites on Mid-Autumn Festival night.
