In a future where North America has been split into four major regions, a ruthless and ambitious corporation has seized control of the traditional prison system. Instead of guards and wardens, the company has turned convicted criminals into the new enforcers of their own kind. The mastermind behind this operation is nanoscientist Eion Prescott, who has developed a terrifying weapon: a nanotech virus named Onyx. This deadly virus is spread through wrist worn devices that resemble ordinary watches, each one locked onto a criminal. Once infected, the prisoners are forced to participate in a brutal game of survival where the only way to earn freedom is to eliminate one another. The question remains: who has the strength and cunning to bring down the corporation’s entire twisted system from the inside?
