The government secretly developed a ubiquitous artificial intelligence that can analyze everyone's behavior, conversations, and online traces through round-the-clock surveillance, and ultimately predict in advance who will fall into the vortex of violence. But the irony is that the government only cares about national security - only major cases such as terrorist attacks are worthy of "machine" action, but the lives and deaths of ordinary people are selectively ignored. As a result, the genius programmer was soft-hearted and left a backdoor behind the government's back to secretly receive "civilian numbers screened out by the machine" every day. What the hell is this number? Every appearance means that someone will become a victim or a perpetrator in the near future - but who is good and who is bad depends entirely on human investigation. A talented programmer teamed up with a former agent who was living on the street with incredible combat prowess. The two became a grassroots "redemption team" - one was responsible for using the brain, and the other was responsible for the hands, racing against unknown dangers every day. You never know whether there is an angel or a devil hiding behind the number in front of you. Every case is an extreme challenge spanning life and death, morality, good and evil.
