Developed for television by Frank Darabont, the series is based on the eponymous series of comic books by Robert Kirkman, Tony Moore, and Charlie Adlard.
Mainly set at the Greene Family Farm, after the escape and destruction of the CDC, the season continues the story of Rick Grimes (Andrew Lincoln) and his group of survivors as they continue to survive in a post-apocalyptic world overrun by flesh-eating zombies, dubbed “walkers”. After leaving Atlanta, Rick and the group are stopped on the highway by a threat unlike anything they have seen before. While searching for someone who has gone missing, the group eventually discovers an isolated farm, where tensions arise among members of the main group, and the mysterious and ignorant inhabitants of the farm, whose secrets and motives are unclear. In the midst of events, Rick and the others try to restore order after a terrible discovery as differences begin to openly erupt between Rick and Shane Walsh (Jon Bernthal).
