Mortician Blake bets everything on a bunker, thinking he has outsmarted the zombie apocalypse. Instead, the disaster never happens, his records are erased, and he is left to face Chloe—another so-called reborn survivor. Their shared light-driven alien parasites are linked to zombie outbreaks across parallel worlds, and when the Blood Moon sends their world collapsing, Blake is forced into a new reality with an endless curse: spreading the apocalypse again and again.
