This set contains all six episodes from the initial season of AMC's zombie series The Walking Dead starring Andrew Lincoln as Rick, a small-town Georgia cop who helps lead a band of survivors after he wakes up from a coma to discover that a zombie epidemic has swept across the country.

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.
