If you call the light, you will inevitably battle the darkness.

Brady is a high school senior, the champion of the outcast and bullied, who becomes the unwitting recipient of a gift that is both beautiful and terrifying. He discovers he can talk to angels and draw down a magnificent and mysterious light from the Blessed Virgin. However, Brady soon realizes that such power comes at a price: If you call the light, you will inevitably battle the darkness.

Indeed, a malevolent darkness is racing toward a small town outside of Dayton, Ohio - transported in a rusted, white conversion van. Its driver brings a palpable evil, unique in its seemingly aimless cruelty. Arrogant and vicious, Ray has no idea of the role he plays in his Master's plan. This evil has the purpose of snuffing out a holy foe before it grows stronger.

1970s Beavercreek, Ohio is a small, Air Force base town. With lots of folks continually moving in and out, the community is slow to take notice when teenage girls start disappearing.

However, as darkness descends and violence intensifies around him, Brady realizes that he is in a life-and-death struggle - not against school bullies, nor merely flesh and blood - but against a strange man with a leering smile who carries Satan in his soul.

In an epic battle of good versus evil, Brady will fulfill a prophecy that is hidden in the vaults of the Vatican...but only if he follows the laws of the Prayer of Vengeance.
