Programmer Li Yuan is framed by his boss and ex-girlfriend, who conspire to pin the company's data breach on him. He is forced to sign an admission of responsibility and accept a massive compensation bill. Pretending to give in while secretly preparing his counterattack, he exposes the fact that the company's core patent has already expired and that his former colleagues have unlawfully stolen the encryption technology he independently developed. At a funding presentation, Li Yuan publicly exposes their technological fraud and defeats their deeply flawed system in a live demonstration, striking back against those who betrayed him and staging a spectacular comeback in the workplace.
