With much of the future world's population rendered into an undead horde, R is a young, and oddly introspective, zombie. On a feeding encounter with a human gathering party, R meets Julie and feels an urge to protect her. What happens with that is the beginnings of a strangely warm relationship that causes R to start to regain his humanity. As this change spreads throughout the undead population, Julie and R eventually find they are facing a larger issue even as their friendship is challenged. Caught between the paranoid human forces and the ferocious Bonie zombies who are a mutual threat, R and Julie must find a way to bridge the sides to fight for a better world no one thought possible.
