Frank Darabont's new series The Walking Dead will air its first six-episode season later this fall. The series is based off the comic book series by Robert Kirkman. The series stars Andrew Lincoln, Jon Bernthal, Jeffrey DeMunn, Sarah Wayne Callies, Laurie Holden, Steven Yeun and Michael Rooker. Here's the full synopsis for the series below.

The Walking Dead tells the story of the months and years that follow after a zombie apocalypse. It follows a group of survivors, led by police officer Rick Grimes, who travel in search of a safe and secure home. The comic goes on to explore the challenges of life in a world overrun by zombies who take a toll on the survivors, and sometimes the interpersonal conflicts present a greater danger to their continuing survival than the zombies that roam the country. Over time, the characters are changed by the constant exposure to death and some grow willing to do anything to survive.
