In order to find out the truth about the murder of his parents, the high-IQ genius Zhou You joins the mystery variety show "Mystery Master" as a contestant. With psychological tricks, cognitive misdirection and environmental manipulation, he repeatedly suppresses the criminal investigation team led by the famous detective Li Mu in multiple rounds of high-IQ duels such as secret room murders, public opinion trials, and stolen paintings. As the program upgraded to a real-life life-and-death game on the Forgotten Island, the mysterious "Phantom" organization and the research on the "Heart of Origin" left behind by parents surfaced one after another. Third-party armed forces broke the rules of the game. Zhou You and Li Mu turned from old enemies to allies, and jointly uncovered secrets that had been sealed for many years. A new crisis quietly came at the end.
