Season 4 - Z Nation

Murphy and Warren find themselves alive in Zona, a zombie free playground for billionaires. Meanwhile, the rest of our heroes are fighting alongside the last of the humans against the mutated Zombie Virus and the unkillable “MAD-Z's.” Warren's mysterious dream of a black rainbow and flesh-eating black rain propels the season forward and puts our heroes in the middle of an even worse Zompocalypse.
