The year is 2808. The place: Oedo, a cybernetic megalopolis of the future where the dreams of a brighter tomorrow are drowning in a tide of violence, vice and villainy. Driven to breaking point, the forces of law and order are left with no choice but to use the very criminals they capture to help hunt their own kind. Enter hardened cyber criminals Sengoku, Gogul, and Benten. Presented by Police chief Hasegawa with a stark choice, they must decide to either rot in jail for the rest of their lives or join a special force of the Cyber Police and possibly get one more chance at freedom. With their less than subtle blend of extreme violence and excessive swearing, some hard justice is coming to Oedo. With each criminal apprehended and each successful mission completed, the state will agree to reduce their sentences. But with each of them serving a 300-year stretch, and Hasegawa keeping them in line with explosive collars, will they survive long enough to be free men once again?
