It's time for the Apocalypse: Part 2. Z Nation's sophomore season will kick off with a bang (litteraly), and Murphy's little nuclear disaster will have Operation Bitemark on the run.

'Z Nation' Season 2: Murphy Is 'Naked & Running', A New Bounty Hunter Joins The Race

Titled "The Murph," the season 2 premiere will open just moments after the finale. Nukes are on their way, Northern Lights is in danger, and Murphy (Keith Allan) is in the wind, albeit with a bounty on his head. Addy (Anastasia Baranova) and Mack (Michael Welch), meanwhile, will still be hanging with the Sisters of Mercy. All in all, it's not looking good for the westward bound survivors.

"It's sort of like a second apocalypse hits at the beginning of the season. It's a game changer for everybody," executive producer Karl Schaefer told EnStars at San Diego Comic-Con. "It's like season 1 on steroids."

Cassandra (Pisay Pao), however, will have the most to get used to. Murphy saved her life, but life came at a price - one that left Sunshine as a quasi-zombie. Now equipped with super speed and strength, Pao's character will have to adjust to a completely different life style in season 2.
