The Walking Dead tells the story of the aftermath of a zombie apocalypse, following a small group of survivors traveling across the United States in search of a new home away from the hordes of undead—colloquially known as 'walkers.' The series centers on sheriff's deputy Rick Grimes, who wakes up from a coma to find the world irrevocably changed and civilization collapsed. As the group struggles to survive, they encounter various threats, not only from the walkers but from other human survivors who have formed their own factions, often with conflicting moral codes and survival strategies. The series explores the psychological toll of the apocalypse, the breakdown of societal norms, and the lengths to which individuals will go to protect their loved ones in a world where the line between hero and villain is constantly blurred.
