Written by Gary Whitta, the screenwriter behind The Book of Eli starring Denzel Washington and the upcoming film, After Earth starring Will Smith, episode four of The Walking Dead continues the story of Lee Everett in the bleak and horrific aftermath of a zombie apocalypse.
As episode four begins, and in the wake of terrible loss, the group of survivors arrives in Savannah, Georgia. Stalked by an unseen human threat and with the constant menace of the undead, Lee struggles to manage the tensions of an increasingly paranoid group and above all, protect 8-year old Clementine, a girl in search of her parents in the wake of the undead plague.
