In The Walking Dead, Sheriff's deputy Rick Grimes awakens from a coma to find a post-apocalyptic world dominated by flesh-eating zombies. He tries his best to keep everybody from dying, or worse, becoming undead. Society has fallen apart, and a cure seems to be out of the question. And with stakes that high, in-fighting is bound to develop among the living. Rick doesn't just have to protect everyone from the walkers; he has to protect them from themselves too.
