'Walking Dead' Preview: This Is What Happens 'When The Dead Come Knocking'

The worlds of "The Walking Dead" are on a collision course. In one corner is the prison, led by Rick Grimes. In the other is Woodbury, led by The Governor. These two men have yet to meet, but thanks to a mutual individual in their lives, they're certainly about to — assuming this aforementioned individual survives next week's episode, that is. And based on the preview clip below, we aren't too sure about her odds.

"Walking Dead" continues its third season next Sunday at 9 p.m. ET on AMC.
