The Walking Dead Episode 510: Extended "Them" Sneak Preview Released

AMC has released an extended preview for next week's episode of The Walking Dead, "Them."

In the clip, Rick and his crew battle an all-too common threat—and it's not zombies. In this instance, this group must stave off the forces of exhaustion as they hike in the southern heat. With no food, water, or reprieve in sight, not even the battle-ready Michonne is up for a skirmish with the zombies slowly following their trail. But Sasha, still reeling from the midseason finale's tragic events, is anxious to put her anger to good use. But as Michonne warns, acting out of anger never ends well.

Check out the full video below.

The Walking Dead returns next Sunday at 10:00 p.m. on AMC.
