"Out of the ashes of a devastated Woodbury, Georgia, two opposing camps of ragtag survivors are on a collision course. Underground, in the labyrinth of ancient tunnels and mine shafts, Lilly Caul and her motley crew of senior citizens, misfits, and children struggle to build a new life. Way out in the hinterlands, amidst the rising tide of walkers that seem to be pushing in from all directions, the psychotic Reverend Jeremiah Garlitz rebuilds his army of followers with a diabolical secret weapon. He has designs on the destruction of Lilly and her crew and now he has the means to bring a special brand of hell down upon the tunnel dwellers."-- Provided by publisher.
