Qin Wenxiu, a stay-at-home mom, won a 10-billion-dollar lottery. She planned to celebrate with her family but discovered her husband's affair with his past love, Xu Mingli, and their divorce plan, with her sons supporting their father. Heartbroken, Qin Wenxiu decided to divorce and start a new life. When she bought a villa with her own money, she was humiliated by her ex-husband's family but exposed their wrongdoings, turning the tables on them. Qin Wenxiu then began investing and, during a business meeting, attended her son's wedding, where she was insulted again by her ex-husband's family. Wang Yaojun's son, Wang Haoxuan, saved the day by revealing that Qin Wenxiu was an investor, leaving them stunned. Later, Xu Mingli tried to scam Qin Wenxiu, but Qin Wenxiu turned the tables, and the authorities arrested her ex-husband's family.
