he Walking Dead tells the story of a small group of survivors living in the aftermath of a zombie apocalypse.[18] The first season takes place in the Atlanta metropolitan area, and the second through fourth seasons are set in the surrounding countryside of northern Georgia. Survivors search for a safe haven away from the shuffling hordes of predatory "walkers" or "biters" – as zombies are called – that eat any living thing they catch, and whose bite is quickly lethal to humans. The plot focuses primarily on the dilemmas the group faces as they struggle to maintain their humanity during the day-to-day challenges of surviving in a chaotic world full of zombie hordes and hostile human survivors.
