In a post-apocalyptic future, a deadly virus has wiped out most of humanity. The only ones who survived, was those who hadn't yet reached puberty. Now a decade has gone by, and a man called Jeremiah (Luke Perry) is set on a quest to find a mysterious place his father spoke of, a place called Valhalla. Written by Fredrik Adolvsson 15 years after a virus wiped out everyone who had passed puberty, the survivors are living on the scraps of the old world. Now they must either continue the downward slide, or begin to rebuild the world, taking responsibility for themselves and the world and each other. Written by Anonymous Jeremiah is set in a future post-apocalyptic world where, almost a decade before, a deadly virus wiped out the world's adult population sparing only those who haven't reached puberty. Now in their 20s, the oldest survivors of the pandemic include Jeremiah and the colorful but cynical Kurdy. Jeremiah is on a personal quest to relocate a mysterious place called Valhalla, which his father claimed might hold some hope for the survivors. As Jeremiah falls into a reluctant partnership with Kurdy, both explore new areas and encounter other groups of young adults who are divided into rival social groups. In the course of the season opener, Jeremiah's smaller personal quest is redirected when he discovers a group of highly organized survivors who want to enlist him to orchestrate peace among the warring factions and to try and prevent the killer virus from returning.
