Zhou Chunmei marries far from home and faces constant criticism from her mother-in-law. She uses her dowry to support her husband's business, but his reckless expansion and an unreliable business partner leave the family drowning in debt. Despite being ill and caring for her sick daughter, she starts over by selling vegetables. Her chicken-farming venture then loses 23,000 yuan to a poultry epidemic. When her mother-in-law needs 30,000 yuan for surgery, Chunmei borrows money and endures ridicule. Inspired by chili peppers, she switches to growing them, overcoming diseased seedlings, torrential rain, poor sales, and even having her fresh peppers trampled after selling them through a livestream. Her husband's casual remark, "They're crushed into chili sauce," gives her an idea. Despite her swollen hands, she experiments with making chili sauce, persevering through failures and malicious reports. The couple sells out their entire stock during a livestream, attracting eager factory owners and inspiring villagers to grow chilies too. Chunmei establishes unified production standards and turns the village into a thriving chili-growing industry. She pays off the debts, buys a car, builds a new house, and finally earns her mother-in-law's approval, becoming known as the "Chili Pepper Lady."
