The Walking Dead tells the story of the aftermath of a zombie apocalypse; it follows a small group of survivors, traveling across the desolate United States in search of a new home away from the shuffling hordes of the undead. The group is led by Rick Grimes, who was a sheriff's deputy in a small Georgia town, before the zombie outbreak. As their situation grows more and more grim, the group's desperation to survive pushes them to the brink of insanity. At every turn they are faced with unspeakable horrors—both from the dead, and from the scattered remains of a struggling human populace.
