When he was six, Gu Yuan witnessed his neighbor secretly swapping his newborn younger brother with another baby while his mother was asleep. That very night, he personally switched the babies back. Eighteen years later, the Gu family is set to receive eight apartments and 50 million in demolition compensation. But Zhao Tianyu shows up with a forged birth certificate, claiming to be their biological son and conspiring with his family to steal their fortune. Everyone thinks Gu Yuan is just an ordinary construction contractor, unaware that he is actually the mastermind behind a trillion-yuan business empire. Faced with an elaborate scam, Gu Yuan chooses not to expose it immediately. Instead, he secretly gathers evidence, waiting for the Zhao family to incriminate themselves. Just when Zhao Tianyu reaches the pinnacle of success, Gu Yuan publicly reveals the truth about what happened eighteen years ago and sends the entire greedy family to prison.
