 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.
