For the second time in her marriage, Mariah White catches her husband with another woman, and Faith, their seven-year-old daughter, witnesses every painful minute. In the aftermath of a sudden divorce, Mariah struggles with depression and Faith seeks solace in a new friend - a friend who may or may not be imaginary. Faith talks to her "Guard" constantly and begins to recite passages from the Bible - a book she's never read. Fearful for her daughter's sanity, Mariah sends her to several psychiatrists. Yet when Faith develops stigmata and begins to perform miraculous healings, Mariah wonders if her daughter - a girl with no religious background - might indeed be seeing God. As word spreads and controversy heightens, Mariah and Faith are besieged by believers and disbelievers alike; they are caught in a media circus that threatens what little stability they have left. What are you willing to believe? Is Faith a prophet or a troubled little girl? Is Mariah a good mother facing an impossible crisis ... or a charlatan using her daughter to reclaim the attention her unfaithful husband withheld? As the story builds to a climactic battle for custody, Mariah must discover that spirit is not necessarily something that comes from religion but from inside oneself.
