Deep in a Texas cave, the military unearths a five-hundred-year-old corpse, its desiccated flesh teeming with mysterious DNA that can transform mortals into beings of unimaginable power.
Captain Scott Boulder, leader of a Black Ops unit that has been endowed with these superhuman abilities, is among the first to benefit from the find. But when, with the help of a voodoo priestess, the creature is conjured to life, unleashing an ancient evil bent on reinstating its poisonous kind on earth, Scott knows he must return the monster to the grave. But this is no ordinary vampire. Once a brutal torturer in the Spanish Inquisition, it can bend the laws of science and magic in horrifying new ways.
Powerless to fight this evil alone, Scott grudgingly seeks the aid of reclusive anthropologist Leah Maguire, an expert in the mystical rituals of the past. To keep humanity from entering a new Dark Age, Scott and Leah will battle unspeakable horrors and will sacrifice everything they hold dear–perhaps even their own humanity -- to destroy the last vampire.
