As October looms closer, so does a new season of AMC’s ratings juggernaut The Walking Dead.  The network has released a new key art image/poster from the upcoming fourth season, suggesting some sort of break from the prison that was so “safe” last year—even though the trailer for the upcoming season shows Rick and the group settling into a very comfortable lifestyle at the correctional facility.  The official synopsis for the season teases that “the group’s home and new way of life will be thoroughly tested, and their struggle to survive has never been so perilous."

Hit the jump to check out the new poster.  Season four of The Walking Dead premieres on AMC Sunday, October 13th at 9/8c.

Here’s the official synopsis for The Walking Dead season four:

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. Season 4 also introduces several new characters including Bob Stookey (Lawrence Gilliard Jr., The Wire).
