“The Walking Dead” is back Sunday night, and the first four minutes of this season’s premiere, “No Sanctuary” have been released by AMC on its website and Facebook page.

The zombie drama, in its fifth season, picks up where it left off earlier this year in March.

The cast of Andrew Lincoln, Steven Yeun, Chandler Riggs and other returning actors must face the unfamiliar “Sanctuary” they all sought at the end of last season.

To prepare for the premiere, AMC ran a “Zombie Apocalypse Week Marathon” of the entire series leading up to tonight’s episode which will premiere at 9/8c on AMC.
