In a rural village in the 1980s, Lin Xiuzhi works tirelessly to care for her family, yet her biased mother-in-law mistreats her because she gave birth to a daughter. When the family splits up, she is thrown out with nothing and forced to move into a dilapidated house. With nowhere else to turn, she makes a living using her knowledge of wild mountain produce. An elderly herb collector teaches her valuable skills, and she gradually builds a thriving mountain-goods business. Her lazy mother-in-law and younger brother-in-law's family repeatedly scheme against her and make life difficult, eventually falling into debt and poverty. Despite their past cruelty, Lin Xiuzhi chooses to help them, establishing a rule that they must repay their debts through hard work. She opens a mountain-goods shop and leads the village women to prosperity. Her once-cruel relatives finally realize their mistakes. From an oppressed daughter-in-law, she transforms into a respected businesswoman and millionaire, proving her worth through diligence and kindness.
