A brutal cat-torture case that went viral online leads to the exposure of a vast underground criminal network. A massive dark web community has quietly spread into every corner of Jianghai City, and the search for redemption between people begins. Videos of animal torture, execution livestreams, collections of body parts, killers for sale, sinister forces, bounty missions, dark web transaction rankings, and unspeakable secret deals are hidden beneath bizarre websites, catering to the perverted desires of twisted souls. In the battle between light and darkness, a former ally quietly transforms into an agent of darkness. When they meet again, the result is a bloody clash between justice and evil. But the things in need of redemption are not just former comrades who have gone their separate ways. They also include those trapped in the dark web, and Jianghai City itself, teetering beneath its shadow. The cybercrime squad and criminal investigation squad of the Jianghai Public Security Bureau form a special task force to wage a covert war, joining forces to take on cybercriminals and dark web gangs. A high-stakes, silent battle to the death erupts in full force!
