Wen Shuran, who handles business affairs at her company, is asked to arrange a private membership card on behalf of her boss. But team leader Jiang Zhenfeng sets his sights on her. Under the pretext of treating everyone to dinner, he schemes to make her sit at the head of the table, order expensive dishes, and sign the bill, intending to charge everything to her boss's card and leave her holding the bag. Having anticipated his move, Wen Shuran preserves evidence and turns his scheme against him. She changes the payment confirmation to a callback, secretly records conversations, and keeps receipts, exposing his attempts to frame her one step at a time. Enraged and humiliated, Jiang Zhenfeng privately reports falsely low prices, switches suppliers to collect kickbacks, substitutes inferior goods, and even forges evidence to try to send her to prison. Armed with irrefutable proof, Wen Shuran turns the tables, takes down the entire corrupt gang, and earns a promotion through her own abilities. She will not take the blame for anyone else's mess, and she will not pay for anyone else's greed.
