On the eve of National Day, company colleague Jiang Kai ostentatiously invited the whole team to dinner, spending one hundred eighty-eight thousand on a single meal. Everyone thought he was finally being generous for once, but no one knew that he had long set his sights on the one hundred seventy-eight thousand balance in female colleague Shen Nanyi's membership card. To prevent any accidents, Shen Nanyi set a payment password for her membership card in advance. When checking out, Jiang Kai confidently demanded to swipe the card, only to be met with a chilling prompt—incorrect password. As this dinner party is exposed, Shen Nanyi discovers behind it not just a consumer scam, but also hidden years of false expense claims, supplier invoice padding, and corporate interest chains. A contest concerning money, trust, and truth officially begins.
