Here is the official description.
Police officer Rick Grimes wakes from a coma to find the world ravaged by a zombie apocalypse. Nearby, a small group struggles to stay alive as 'the dead' stalk them. Can Rick and the group survive the zombies and each other in this horrific new reality? The Walking Dead is a survival adventure series from the director of The Shawshank Redemption and the producer of The Terminator.
I think this has the possibility to be the next big critical hit at next year's Emmies and hope it isn't hurt by the subject matter (like BSG and Buffy were).
The Trailer for the show is below:
If you are interested in the comic, we did the first volume as part of our Comics Experience Book Club (along with Mr. Kirkman, himself). A description of the event can be found here.
