When billionaire Richard Harrison bequeaths his entire fortune to a psychiatrist, brutally murders his entire family, and then takes his own life, police detective Bright Mugabba can't help but wonder why. As he pursues the truth, he finds himself face to face with something no amount of police training could have prepared him for. On the other side of the world, arson investigator Luca Giggliano discovers that the destruction of the ancient Abbey Starita and the deaths of the monks of the Order are only the beginning of a living nightmare. With seemingly no one left to stop him, the demon, Mobious The Corruptor is now free. His plan to release the rest of The Harbingers is already in motion. And when they have all been freed, hell will follow.
