On the day of his wedding, lawyer Lin Yue faces an unexpected demand from his future mother-in-law, Liu Guixiang, who suddenly insists on an additional 500,000 yuan to help her son buy a house, as well as a monthly allowance of 5,000 yuan for her retirement. His bride, Lin Xue, is timid and submissive, but Lin Yue decisively calls off the wedding and legally demands the return of his 288,000-yuan bride price. When the Liu family throws tantrums, makes threats at his home, and spreads defamatory rumors online, Lin Yue stands firm and fights back with evidence. Along the way, he uncovers a habitual marriage-fraud scheme. With help from others, he exposes the criminal gang, brings everyone involved to justice, and recovers his losses. Refusing to compromise his principles or give in to unreasonable customs, Lin Yue finally leaves the past behind and begins a brand-new life.
