Plot
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 precarious, the group's desperation to survive pushes them to the brink of insanity. At every turn they are faced with the unspeakable horrors that come from having the dead walk again, as well as facing hostility from the scattered remains of a struggling human populace who are focused on their own survival, now that the structures of society have collapsed.
