* The world we knew is gone. The world of commerce and frivolous necessity has been replaced by a world of survival and responsibility. An epidemic of apocalyptic proportions has swept the globe, causing the dead to rise and feed on the living. In a matter of months society has crumbled: no government, no grocery stores, no mail delivery, no cable TV. In a world ruled by the dead, the survivors are forced to finally start living.
* As the survivors settle into their prison home something has drawn them out into the open... out of the prison... out of their sanctuary. This is a major turning point for the overall story of The Walking Dead, setting the stage for years to come.
