The eternal battle between Heaven and Hell rages on with your soul as the prize. All that stands between them and us are the Combat Exorcists, sworn to knock demons back into hell through their unique mastery of the God flow — the ability to channel the unique traits of divine beings from different levels of angels to old testament creatures to horrific beasts featured in the Book of Revelation.

Syd Miller and Ellen Blair are the world's two premiere Combat Exorcists — the only problem? After a nuclear break up years ago, they can't stand each other. But when the biggest soul auction in history kicks off beneath Los Angeles, Syd and Ellen have no choice but to come together to raid the HELLSCRAPER, an infernal tower going straight down into the Earth. With thousands of souls on the line, Syd and Ellen must fight their way to the bottom, or die trying.
