Lu Chen sneaked into the "Darknet Nest" as an undercover agent, but met the mysterious female technical officer Su Qingyan during the mission-sometimes she solved the case coldly, and sometimes she was ruthless and bloodthirsty. The contrast between her dual personalities made him suspicious. As the contact deepened, Lu Chen discovered that there was a chaotic cause and effect cycle hidden in the organization: the intelligence he intercepted today would actually become the cause of the murder of his colleagues yesterday. Hypocritical bosses and selfish colleagues set up traps one after another, and his inner demons and identity conflicts continue to tear him apart. Su Qingyan's dual identity is more like a double-edged sword. It is both his ally and the obstacle that drags him into the abyss. In the web of betrayal and cause and effect, Lu Chen must rely on golden fingers to "deduct cause and effect" to break the game, but he does not know that he is already a pawn on someone else's chessboard.
