“The Walking Dead” Season Premiere Sunday, October 7 on AMC at 9PM [Videos]

The new season and the last for Rick Grimes (Andrew Lincoln) opens 18 months after the end of the all-out war against the Saviors and will focus on how life has evolved in the years since the zombie apocalypse.

Last season brought the culmination of “All Out War,” which pitted Rick Grimes and his group of survivors against the Saviors and their cunning leader, Negan. With Negan’s life in his hands, Rick had a character-defining choice in front of him. By making the unilateral decision to spare Negan, Rick upheld the values his late son, Carl, championed in order to build for the future, but created conflict within his group.

Now, we see our survivors a year and a half after the end of the war, rebuilding civilization under Rick’s steadfast leadership. It is a time of relative peace among the communities as they work together, looking to the past to forge the future, but the world they knew is rapidly changing as man-made structures continue to degrade, and nature takes over, changing the landscape and creating new challenges for our survivors.

As time passes, the communities confront unexpected obstacles, danger, and of course, walkers, but nothing quite prepares them for the formidable force they are about to encounter, which threatens the very idea of civilization that our survivors have worked so hard to build.
