The Walking Dead Premiere Preview: House to House

"We can't go house to house anymore," Rick tells his band of survivors in a new preview of the third season premiere of The Walking Dead, coming Sunday on AMC. They have to find someplace to stay, is his logic--which of course fans know to mean the prison, but in this tense preview all it explicitly says is that they've been circling the area for the summer, trying to avoid a herd of around 150 walkers. Check out the video below, and stay tuned for much more on The Walking Dead this week!
