After the zombie apocalypse people learned how to harness zombies for power. Zombies became their own unit of energy, providing power and electricity for a recovering world. The D-Tec Corporation builds, powers, and services zombie-powered devices; from power plants, to factories, to 'single-zombie' portable generators. They are rebuilding that which was lost in the zombie apocalypse with the very agents that destroyed it. Tired of the isolation of living in the wilds, Tyler allowed himself to be recruited by the Corporation. Bringing a lifetime of knowledge in dealing with the undead, he became a star employee as a stoker in the Corporation's Fargo power plant. A stoker's job was to maintain the proper level of zombie aggression. Too little anger and the city's lights would dim. Too much anger and the zombies would fall apart too quickly, a costly resource. Tyler was good at his work and life was good in Fargo, until he became bored and asked for change.

When a highly skilled doctor's son is killed in war, he creates a biological mutagen meant to heal other seriously injured soldiers. Unfortunately, the cure quickly spreads and infects the rest of the human race, turning its victims into violent monsters. John Smith (yes, John Smith) leads local survivors to safety, while soldiers Eric Labelle and Ross Thompson begin making their way home from Iraq, and Army Drill Sergeant Aaron Baccharus recovers from a life threatening illness to begin changing the course of the mutant plague.
