The Walking Dead Season 1

Rick, while on his sheriff's patrol duty with his partner Shane Walsh, is injured and falls into a coma. He awakens some time after the apocalypse and meets survivor Morgan Jones, who explains the dangers of walkers. Rick travels to Atlanta, Georgia, in search of his family only to find that city has been overrun by walkers. Rescued by Glenn Rhee, Rick is eventually introduced to the rest of Glenn's group, who are camping a few miles outside of the city. There, he discovers that his wife Lori and son Carl have been living with Shane. The two policemen employ different approaches to keep the peace: Rick returns to Atlanta for supplies and to retrieve a man left behind, while Shane exerts his authority over the camp.

When the camp is overrun by walkers, Rick and Shane convince most of the survivors to head for the Centers for Disease Control (CDC) in Atlanta. They briefly shelter with the only remaining CDC staff member, who has been unable to develop a cure, before a protocol incinerates the facility.
