Damien is a demon bound to human form to protect a child born to a bloodline of oracles. Years later, the child is now a teenager having visions of a coming apocalypse. One night there is a knock on the door and two young women turn up asking for help. At first Damien refuses, but with the visions of his young friend starting to come true, he realizes that if he doesn't protect them, the world might just end. The last thing he expected was to fall in love. As demons and creatures from the supernatural world stream into the streets it's up to Damien to put an end to the violence. With the help of a sarcastic vampire, a retired druid, and a few friends they make along the way, Damien must fight against the odds to remove the threat to his world and to the people he loves.
