Tian Xiaoshu, an ordinary convenience store worker, vows to dedicate herself to public anti-fraud education after her college friend dies by suicide after falling victim to a task-based online shopping scam. While running the store, she records short videos exposing various scams, taking on pension investment schemes, livestream appraisal tricks, bank card lending traps that aid criminal activity, and romance scams. Even when she faces online harassment from paid trolls and threats from acquaintances colluding with fraud rings, she refuses to back down. She also enlists her family and friends to assist the police, gradually uncovering a major fraud syndicate using loan-sharking, AI face-swapping, and forged financial institution identities. Drawing on her own experiences, she warns the public to protect their assets and demonstrates the power of collective anti-fraud efforts.
