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 divorce, Mariah struggles with depression and Faith seeks solace in a new 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. 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, and what little stability they have left is threatened.
