Thirteen years ago, Orin McCabe was a family man living a privileged life in the California suburbs. Today, he's condemned to death row for murdering his entire family in an unexpected fit of hammer-wielding brutality. In the aftermath of his heinous crime, it's fallen to a trio of eclectic, but dedicated, ghost hunters—Jacob, the holy man; Holland, the skeptic; and their leader, Del, a true believer in the occult and worlds beyond—to surveil the abandoned McCabe home in search of proof for the existence of the undead . . . and whatever supernatural source may have possibly fueled McCabe’s inhuman massacre. But this ill-matched and uneasy squad of investigators is about to discover something much more terrifying than any ordinary spirit. . . . Something much more pernicious, much more contagious, that if not contained, could take full advantage of America's unquenchable appetite for violence and deliver a plague of blood unto us all . . .
