A disavowed priest and nun in love are pursued by demons who seek the blood of their unbaptized baby as the final ingredient for an ELIXIR that will change the world forever. It begins as a story of a priest and nun, Father Tom and Sister Christina, both well-respected teachers at a Catholic school in San Francisco. One night, they are caught embracing by a corrupt Mother Superior, setting off tumultuous supernatural events that force them to escape to save their lives. But it’s all a set up for a predatory mission by the Underworld with a greater purpose. Now civilians, Tom and Christina are pursued by demons, who lurk constantly in the shadows and wait patiently for them to adjust to a new life in Oregon, marry, and have their first child, a son. What follows is a prolonged nightmare for the couple as they fight for their lives and deal with the conflicts between them.
