Z NATION follows a team of everyday heroes on their epic struggle to save humanity from the Zompocalypse. Season 4 begins with a mind-bending jump in time. Murphy and Warren find themselves alive in Zona, the zombie-free playground for billionaires. Meanwhile, the rest of our heroes are fighting alongside the last of the humans, against a mutated Zombie Virus and the unkillable "MAD-Z’s" the mutation causes. Warren's mysterious dream of a black rainbow and flesh-eating rain, propels the season forward and puts our heroes at the center of an even worse End Times. Here they will have to battle; Freak Enders, Mysterious KidnapperZ, Franken-Zombies, Juggalo Z’s, NunZ’s, Rat-Z's — and if that weren’t bad enough, to save the Apocalypse. Our Heroes must find the Zombified President of the United States - or at least his thumb.
