The fourth season of The Walking Dead finds Rick Grimes (Andrew Lincoln) desperate to rediscover his own humanity and preserve what he can of his son Carl's (Chandler Riggs) childhood through reinventing himself as a farmer while a counsel including Carol (Melissa McBride) and Daryl (Norman Reedus) in addition to several Woodbury ex-pats take on leadership roles. His newfound sense of peace is quickly derailed, however, when a mysterious illness begins to decimate the community. Elsewhere, the disgraced Governor (David Morrissey) roams the apocalyptic streets on his own until happening upon a family of survivors who reignite both his will to survive and take revenge against Rick, who he blames for the loss of Woodbury. Following a massacre at the prison, the group is splintered into several factions, none of whom can be sure about the fates of the others, and forced to find shelter among a population of survivors that can pose as much and often more of a threat than the walkers themselves.

In addition to the environmental dangers for the globe, the series offers footage of animals as they adjust to these changes conditions, as well as the natural shifts that occur as the seasons change in these extreme climates. Alister Fothergill, the man who oversaw both Planet Earth and The Blue Planet: Seas of Life, served as executive producer for this project as well.

The third season of The Walking Dead finds Rick Grimes (Andrew Lincoln) taking on a more dictatorial role than in the past as he and the group work to make an abandoned prison their new, fortified home in a zombie infested world. However, they soon learn the harsh lesson that they must fear fellow survivors in addition to the walking dead, as a new threat rises in the form of the megalomaniacal "Governor" (David Morrissey) and several surviving prison inmates.
