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.
