Chen Jin has been undercover for seven years. On the night his identity was exposed, he set fire to the police station with his own hands and defected to the Red Flame Society with evidence that could overturn the city's shady plot. Shen Yuan, the woman who once pushed him into the abyss with her own hands, is now secretly cleaning up his body and modifying his data. Lao Scar's severed finger, Ah Jiu's chip, Zhou Lin's lies, and Aunt Bai's suicide note, each of them forced him to realize that he was not an undercover agent, but a torch being used as a chess piece. When the name of his teammate appears in the evidence list, he must choose the version that can survive between destruction and redemption.
