Just before the turn of the millennium, Jonas (Rami Malek) was a clean-cut man with a wife and young daughter. He had a steady job as a night shift concierge and was hoping to save enough to buy a plot of land in the wilderness so they could all live in the country.
However, Jonas has apocalyptic visions of Y2K, and a chance encounter with a mysterious drifter (DJ Qualls) who shares his visions leads to mysterious events that find Jonas now known as Buster, a mountain man and fugitive.
