When the Infected horde breaches the ranch's defenses, all hell breaks loose.

The survivors hide out in the pantry, but the air vent breaks, making their refuge just as deadly as the world outside.

As Executive Producer Gale Anne Hurd says in a new behind-the-scenes video on Episode 13, "Our characters, including Alicia, are in serious jeopardy."

Alicia, who led the group into the pantry, feels the weight of the world on her shoulders.

But, she couldn't predict the fresh horror waiting on the other side of the pantry doors.

"It's the safest place, with all the supplies," explains Alycia Denbam-Carey. "It logically all makes sense."

To add to the pressure, Alicia asks the survivors who have been bitten to voluntarily give up their lives so that the rest of the community can conserve air and buy themselves some more time.
