AMC released a 4-minute-long preview video for the upcoming fourth season of “The Walking Dead” that’s loaded with new footage.

“In the highly anticipated new season, we find Rick Grimes (Andrew Lincoln) and the group fostering a thriving community in the safe haven of the prison. Sadly, in this brutal world, happiness is short-lived and walkers and outside threats are no match for danger brewing inside the fences. The group’s home and new way of life will be thoroughly tested, and their struggle to survive has never been so perilous.”

Based on the comic book series written by Robert Kirkman and published by Image Comics, “The Walking Dead” tells the story of a group of survivors who travel in search of a safe and secure home in the months and years following a zombie apocalypse. The series stars Andrew Lincoln, David Morrissey, Steven Yeun, Norman Reedus, Danai Gurira, Chandler Riggs, Lauren Cohan, Scott Wilson, Melissa McBride, Chad Coleman, Sonequa Martin-Green, and Emily Kinney.

Season 4 of “The Walking Dead” returns to AMC in October 13 at 9pm ET.
