Natalie Brandon doesn't believe in curses - except the one afflicting her. Diagnosed with schizophrenia, she's tormented by a recurring hallucination - the voice of an angel named Belial. When her boss acquires a copy of the rare 1631 Sinners' Bible, Belial tells her that the book is linked to the tragic Stuart dynasty - and the curse that brought it down. Natalie doesn't believe it until the public unveiling of the book goes horribly awry. A pair of thieves take Natalie, her sister, and her boss hostage. When Belial orders her to keep the thieves from stealing the Sinners' Bible, Natalie knows it's because he wants to unleash the curse once more. Will she stop the thieves or will she stop Belial? No matter which choice she makes, someone will die.
