Revelations

Harvard professor Dr. Richard Massey is an astrophysicist who's certain that all worldly events can be explained by science. He is challenged by Sister Josepha Montafiore, a devout nun who leads him on a quest through a world of true believers, heretics and Satanists. Drawn together by personal tragedy, they are swept into a deepening mystery when they discover evidence that the world, as predicted by The Book of Revelations, has reached The End of Days.
