The world is on fire.

Amid the eruption of a cataclysmic third world war, monks Sergius and Herman are sent from Russia to Virginia to find holy relics believed vital to humanity in a time when life is on the cusp of extinction.

Quiet introvert Stephanie and her family live in Fairview, Virginia, a town like most in America, hollowed out by crime and oppression, that's tearing Stephanie's family apart.

When the monks' journey takes them to Fairview, they meet Stephanie at the last remaining church in town. Their collective prayers and the holy relics may be the only things that can save themselves and the world.
