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 begins to confide in an imaginary friend. At first, Mariah dismisses these exchanges as a child's imagination. But when Faith starts reciting passages from the Bible, 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, caught in a media circus that threatens what little stability they have left.
