Bob the Zombie managed to escape Detroit (in Motor City Shambler), but now he and his fellow zombies are starving in Flint, Michigan. Inside a former community center, the human residents put up a fearsome resistance and the Zombies--generally a slow-thinking lot--seem doomed to starve rather than enjoy that nice human flesh. Fortunately for them, Bob is one of the rare thinking zombies. He comes up with a plan to use hammers and a chainsaw to gain entrance. For the zombies, any success is temporary. They need to eat living or recently dead humans to keep their semi-alive bodies from collapsing. Success in Flint is merely one step in a journey after more food, more human bodies. Meanwhile government scientists are kidnapping zombies. Soon, we fear, the humans will find a counter to the undead shamblers--but Bob intends to save as many of his fellow zombies for as long as he can.
