Before Double Eleven, Zhu Ning prepares a celebration banquet for her company. Her boyfriend's sister, Shen Miao, persuades her to book tables using family ties and half-price seafood. On the day of the banquet, twenty tables become ten, ten people are crammed into twenty, and the cost surges from 100,000 to 212,000. Not only does her boyfriend refuse to help, but he also advises her to pad the expense report. Zhu Ning decisively cancels the banquet, switches to issuing buffet vouchers to spend the money on her employees, and publicly announces the breakup. Enraged, the sister and brother resort to claims, intercepting recordings, and spreading rumors to destroy her business. Zhu Ning uses original footage and business records to debunk the lies item by item, and the father brought by Shen Miao turns around to audit the accounts instead. In the end, the schemers lose trust, and Zhu Ning wins back her career and freedom.
