What did the world look like as it was transforming into the horrifying apocalypse depicted in "The Walking Dead"? This spin-off set in Los Angeles, following new characters as they face the beginning of the end of the world, will answer that question.

Some of Sin City's most hard-boiled citizens cross paths with a few of its more reviled inhabitants.

One day, electricity just stopped working and the world was suddenly thrust back into the dark ages. Now, 15 years later, a young woman's life is dramatically changed when a local militia arrives and kills her father, who mysteriously—and unbeknownst to her—had something to do with the blackout. An unlikely group sets out off on a daring journey to find answers about the past in the hopes of reclaiming the future.
