The Walking Dead - Season 1

Sheriff's Deputy Rick Grimes is shot and wounded in an altercation with criminals. After slipping into a coma for an indeterminate amount of time, Rick awakens in an abandoned hospital to find a post-apocalyptic world overrun by infectious zombies, colloquially called "walkers". Rick discovers that his wife and son are missing and meets survivors Morgan Jones and his son Duane, who take him in and explain the situation to him. Rick leaves Morgan with a radio in order to keep him updated, as he heavily arms himself from the police station's armory and sets off on a perilous journey for Atlanta, Georgia. The Centers for Disease Control and Prevention (CDC) is rumored to have set up a quarantined safe zone in the city and Rick believes that his family may be there. However, he soon discovers that the city has been overrun with walkers and is no longer safe. After being rescued from a horde of walkers by Glenn Rhee, Rick meets part of Glenn's group, who had set themselves up in an Atlanta department store. However, walkers attack, forcing them to escape while reluctantly leaving behind Merle Dixon, who had been handcuffed on the roof by Rick due to his unstable and violent behavior.
