‘The Walking Dead': Watch Season 8 Premiere’s First 3 Minutes to See Rick’s Death Vow (Video)

AMC’s flagship series returns Oct. 22

Rick Grimes (Andrew Lincoln) gives the pep talk to end all pep talks in a sneak peek at the upcoming Season 8 premiere of “The Walking Dead.”

The hit AMC zombie series released the episode’s first three minutes on social media on Friday, giving fans an early look at their heroes preparing for battle.

“Those who use and take and kill to carve out the world and make it theirs alone, we end them,” Rick says in the footage. “We don’t celebrate it — we don’t have shame about it, either. There’s only one person that has to die, and I will kill ‘em myself. I will! I will.”

The promo also shows Dwight (Austin Amelio) receiving an ominous message courtesy of a messenger arrow.

The Season 7 finale, which aired in April, ended with Negan (Jeffrey Dean Morgan) bellowing to his followers that war is imminent.

Check out the tense clip in the tweet below.

“The Walking Dead” Season 8 premieres Sunday at 9/8c on AMC.
