After successfully leading his team to crack a major fraud case, the leader of the Anti-Fraud Society, Zeng Miao Zhu, uncovers an even larger conspiracy lurking in the shadows. He then assigns elite members Lam, Arrow, Big Mouth, and Ba Jie to infiltrate the money game controlled by Tang Gang. Their mission is to become the spokespersons for the project, quickly attracting a large influx of funds while simultaneously collecting evidence of criminal activity. However, after Tang Gang reaps enormous profits, the plan takes a sudden turn. Arrow is promoted by Tang Gang to become the spokesperson for a new wave of fraudulent schemes, leading to suspicion and internal conflict within the Anti-Fraud Society. Moreover, the society accidentally discovers that an even more powerful hand is manipulating everything behind the money game. As their investigation deepens, they gradually uncover a horrifying murder case that occurred in China 20 years ago. This long-buried case not only involves local elites but is also intricately linked to the current financial fraud network, plunging the entire Anti-Fraud Society into even greater danger and challenges.
