Taking place five years after the beginning of the outbreak, humans have started a walled-off colony in the city square of Old Watertown New York.
Led by General William Tate, soldiers are exterminating the zombies by the hundreds. But they have seriously underestimated these walking dead, and failed to heed warnings made by the evolved ones, -known among their kind as The Ascended Ones- who wish to live out their existence in peace.
The real battle for human survival begins when The Ascended Ones decide that peace with the living may have never been an option to begin with. And they, along with the legions of lesser, mindless zombies under their control, set out to remove the last threat to their existence.
