The plot takes place in fictional Hope County, Montana. A priest living there named Joseph Seed believes in an imminent collapse of civilization and that he was chosen to protect people from it. He founds the organization "Project at Eden's Gate". The ideology of this sect contains many elements of Christian eschatology, such as the idea of the Seven Seals or the imminent end of the world. However, Eden's Gate is becoming a radical cult, forcing people to join. The members of Eden's Gate and the rest of Hope County are clashing and armed conflicts are developing.
