Walking Dead (2003) 51-A

Rick is recovering as the others go out to forage for food and supplies when something odd happens: the phone rings. Rick learns there are more survivors out there but they won't tell him where they are until they talk it over with the others. Rick and Carl go out hunting but are too late to save a man being attacked by zombies but they do find his car and supplies. Later, Rick gets in contact with the woman on the phone but they are not ready to tell him where they are right now. Rick learns the truth about the phone call. It's all in his mind as he believed he was talking to his dead wife, Lori.
