After surviving a demon attack, disgraced police detective VICTORIA MARTIN tracks down the Valducans in search for answers. Recognizing her potential, and despite the warnings of the other knights, ALLAN HAVLOCK, protector of Ibenus, takes her in as his apprentice.

As the Valducans travel to Paris to destroy a demon nest infesting the catacombs, the knights find themselves hunted by an Internet group intent on exposing them. Victoria, who belongs to this group, must desperately play both sides to not only protect herself, but Allan, whom she has begun to love. Ibenus, however, has other plans.
