The Walking Dead is an American post-apocalyptic horror television series developed by Frank Darabont for AMC that is based on the comic book series by Robert Kirkman, Tony Moore, and Charlie Adlard. Andrew Lincoln plays the show's lead character, sheriff's deputy Rick Grimes, who awakens from a coma to discover a world overrun by zombies, commonly referred to as "walkers". Grimes reunites with his family and becomes the leader of a group of other survivors. Together, they struggle to adapt to a post-apocalyptic world filled with walkers and opposing groups of survivors, who are often more dangerous than the walkers themselves. Much of the series takes place in and around Atlanta, Georgia, and later Alexandria, Virginia.
