For twenty-three years of marriage, seamstress Wen Shuning believed her husband, Lu Jianming, was merely a freight-yard dispatcher earning 4,000 yuan a month. While accompanying their daughter during her college entrance exams, she witnesses Lu Jianming driving a Maybach to take her best friend's son, Zi'ang, to the examination venue. She discovers that her husband is actually the owner of a logistics company and has long been maintaining another family. Determined to uphold her principles, Wen Shuning waits until her daughter finishes the exams before leaving with her. She awakens the dormant assets in her family's trust, hires a lawyer to gather evidence, and uses legal means, including divorce proceedings and a shareholder vote to remove him from office, to reclaim the property he has misappropriated and make Lu Jianming pay the legal price. Mother and daughter begin a completely new life.
