In the not too distant future, a brilliant but twisted military scientist named Dr. James Bent uses a neon military space shuttle to drop his deadly Zone Generators across half of the Earth, thus creating a region called the Spiral Zone due to its shape.
Millions of people are trapped in the dark mists of the Spiral Zone and transformed into "Zoners" with lifeless yellow eyes and strange red patches on their skin. Because they have no will to resist, Dr. James Bent - now known as Overlord - makes them his slave army and controls them from theChrysler Buildingin New York City.
His followers are known as the Black Widows: Bandit, Duchess Dire, Razorback, Reaper, Crook, and Raw Meat. They are immune to the mind-altering effects of the Zone because of a special device called the Widow Maker. However, due to prolonged exposure to the Zone, they display the same physical effects to their bodies as normal people caught inside the Zone, which has dark skies and Zonesporesgrowing in many places. Overlord seeks to conquer the world by bringing everyone under control with the Zone Generators. The Zones feed off human energy, which is why Overlord does not kill anyone inside.
With major cities Zoned, the nations of the world put aside their own differences to fight the Black Widows. However, only five soldiers using special suits to protect themselves from the Zone could do it. While easy to destroy, Zone Generators are impossible to capture because ofbooby traps. Overlord would also drop more generators on remaining military and civilian centers and force the Zone Riders into a standoff.
