“Walking Dead” fans only have a month left before the big Season 9 premiere on AMC and the network is already teasing the upcoming story lines. The premiere is set for Sunday, October 7th just as NYCC comes to a close.

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.

The network teased, “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.”

The long-running series, which is based on the comic book series written by Robert Kirkman and published by Image Comics, still reigns as the number one drama on television among adults 18-49. That’s a title the show has held onto for the last six seasons.

This will be a bittersweet season for longtime fans, since Andrew Lincoln is leaving the show. The star, who has been part of the Walking Dead since its first episode, is calling it quits after the show’s ninth season.

The series is executive produced by chief content officer Scott M. Gimple, showrunner Angela Kang, Robert Kirkman, Gale Anne Hurd, David Alpert, Greg Nicotero, Tom Luse and Denise Huth.
