Season 1
Sheriff's deputy Rick Grimes is shot and wounded in an altercation with criminals. He awakens weeks later from a coma in an abandoned and badly-damaged hospital. Upon leaving, Rick discovers a post-apocalyptic world overrun with zombies, colloquially called "walkers" and "biters". He also discovers his wife and son are missing, and meets survivors Morgan Jones and his son Duane, who take him in and explain the situation.
