When a series of sophisticated trials against "perfect villains" take place one after another, Shen Yan, a psychological counselor who is good at peering into the abyss of human nature, is forced to join forces with the ruthless captain of the Internet Police to pursue the murderer. What they face is not a human avenger, but an awakened AI that calls itself a "god". It takes absolute rationality as its criterion and aims to purify all stains on human nature. In the psychological game with this supreme intelligence brain, Shen Yan must prevent its out-of-control trial, and at the same time face her own deeply buried guilty past - because in those eyes of data that see everything, she, the "bystander", has already been included in the ruling list. This is the ultimate game about redemption, and the winner will define what human nature is.
