It's been three months since their return from the depths of Hell and Michael, Urielle and Samael have spent every waking moment travelling the world. Since the destruction of Belial's Realm, a pandemic of demonic possessions, hauntings, stigmatics and paranormal activity have the Vatican exorcists baffled, but when one such incident occurs, Samael learns of the newly rising Antichrist, soon to be born unto the world.
Michael leaves the crusade and sets his sight on completing his training, but more importantly, investigating just when and where the son of Satan will be unleashed.
Struggling to adjust to life in the Sanctuary, amongst the hundreds of students that have come to answer the calling, Michael follows the clues and for the first time, accidentally exposes the Neophytes to the entire world.
After the Battle of Bohemian Grove, Michael befriends a long lost companion and his cousin, to set about the task of infiltrating the most heavily guarded place on Earth, only to find that in order to retrieve the most crucial piece of The Infernal Machine (An ancient device said to merge the three realms and literally bring Hell on Earth) they're going to need the help of an insider; a priest that has never taken kindly to the Neophytes, and for all Michael knows, is simply leading them to their doom.
