New employee Zhao Yun processes a payment of five million yuan but is repeatedly obstructed and extorted by finance officer Xu Youyou and her brother, director Xu Daqiang. Zhao Yun gathers evidence, including audio recordings and surveillance footage, exposing their scheme to deliberately delay payments and put the company at risk of a fifty-million-yuan breach-of-contract penalty. She subsequently uncovers their other crimes, including money laundering, leaking the minimum bid price of a project, and forging documents. Numerous victimized employees come forward to testify. With her professional solutions, Zhao Yun resolves the compensation claims, secures major business deals, and averts several corporate crises. The chairman overhauls the company and establishes a transparent approval system, while the Xu siblings are sent to prison. Thanks to her outstanding performance, Zhao Yun is promoted to vice president and helps rebuild a fair and efficient corporate environment.
