Lu Ze is reborn ten years in the past. In his previous life, his colleague Zhao Qiang set up an overseas sports betting scam that cost his friend Fatty his life when he jumped off a building. This time, armed with memories of his previous life and exceptional data analysis skills, Lu Ze calmly makes his moves and gradually exposes Zhao Qiang's schemes. When Zhao Qiang strikes back recklessly by embezzling company funds, framing the finance department, and inciting colleagues to launch online attacks, Lu Ze methodically secures the evidence and develops an anti-fraud fund-tracking model. Turning Zhao Qiang's own tricks against him, he lets the man's greed lead to his downfall. When the truth finally comes to light, Zhao Qiang receives a ten-year prison sentence for embezzlement, fraud, and other crimes. Meanwhile, Lu Ze uses his legitimate earnings to establish a data company and becomes a pioneer in combating fraud.
