Lin Xiaoman is the head of industrial business in Nancheng. Formerly struggling in the marketplace, she received the grace of a single meal from Chen Dazhi of the village, and thus hid her business identity to marry into the Chen family of Liuhe, agreeing to repay the kindness and leave after three years. Mother Zhao has a narrow mind, treating Xiaoman like a servant, driving her to live in the woodhouse, and demanding her mother's heirloom bracelet. Xiaoman silently accepts it, secretly paying off debts for the Chen family, donating roads, and building factories, never claiming credit. When the three-year term expires, her traces as the head gradually come to light. Mother Zhao is initially shocked and then greedy, plotting for her property; Dazhi wakes up initially, resolutely protecting his wife. The old enemy Zhou frames the Chen family, Xiaoman clears the account books and reports to officials for investigation. Mother Zhao finally repents, offering soup and returning the bracelet. Xiaoman stays, returning to the village with Dazhi to establish a factory, and the whole village is blessed.
