Watch the New Teaser For The Walking Dead Season Four

AMC has unveiled a new 30-second spot for The Walking Dead, which kicks off its fourth season in less than two weeks.

The teaser shows all hell breaking loose when Walkers apparently infiltrate the prison, where Rick’s group and the Woodbury refugees have been living in a relative peace for several weeks.

The Walking Dead premieres Sunday, October 13 at 9/8c on AMC. Learn more about Season Four in SciFi Stream’s show guide. Also check out the epic Season Four photo galleries!
