From the nuclear devastation of World War III rose the Guardians. Guerrilla freedom fighters in a United States fallen prey to invading forces. They are the last reminder of what
America stood for - and the last hope of what America can be once more.

The Guardians are unwelcome guests in a country on the brink of anarchy. Desperate factions fighting for supremacy have turned Mexico into a blood-soaked killing ground.

Rising from the south-of-the-border rubble is Sister Light. She's leading her Christian hordes on a savage crusade toward a full-auto Armageddon. She must be stopped - at any cost. No matter how many have to die.
