The Walking Dead 9 p.m., AMC
The hit-or-miss AMC zombie drama staggers back into our Sunday nights for 16 more episodes. The action in season three picks up eight months later, and Rick, Lori, and the gang (depleted though it may be) have hit the road and taken up refuge in a prison. They’ll also get to know some folks in the neighboring stronghold of Woodbury. And sword-wielding wunderkind Michonne will make her presence more deeply felt. Pictured: Andrew Lincoln as Rick Grimes.
