Under the city night, an inconspicuous consultation office quietly turned on the lights. It does not receive ordinary customers, but "visitors" trapped in high-tech scams, data nightmares and the abyss of human nature. A team composed of retired soldiers, genius hackers, trauma doctors and mysterious girls, at the intersection of light and shadow, use technology and heartbeat as their blades to cut through the cold calculations and searing scars behind each mystery. They repaired the out-of-control intelligence, tracked the shepherds of the network, and snatched the glimmer of life that was about to sink from the silver-haired trap and the bone-corroding secret. Here, secrets and redemption are of the same price.
