Alexandria is apparently not immune from the walkers threat as seen in a preview for the next episode of "The Walking Dead". The video sees Glenn and Noah running around while holding their guns. There's also a shot of a herd of zombies approaching.

Another scene shows Abraham fighting some walkers. Meanwhile, Gabriel is seen sitting alone and having a serious thought about his situation. Fans will also catch up with Eugene who is featured in a clip from the upcoming outing.

"Spend" airs Sunday, March 13 at 9/8c on AMC. According to the official synopsis, "Rick and his group face a number of challenges while trying to secure their new home."

There are three episodes left in the current fifth season of the series. Melissa McBride, [SPOILER ALERT!] whose character Carol caught viewers by surprise in the latest episode by threatening a young boy, Sam, when she was caught sneaking guns, tells The Hollywood Reporter that the remainder of the season "is a very powerful back-end."

As for the biggest threat to Alexandria, the actress says, "It's other humans, as far as we're concerned. They're so unpredictable."
