For as long as anyone can remember there has always been something a little off about San Luis Obispo, but only a select few have ever known the reason, that the town is sitting directly above a Hellmouth that has only become active in the last decade. Now it's drawing supernaturals of all shapes and sizes, Vampires and Shifters and Werewolves. Disappearances are at an all-time high, animal attacks are on the rise, more and more people are checking into the hospital with suspicious bite wounds on their necks. The supernaturals are taking over.
The Hunters and Slayers, along with their Watchers, can only do so much. It's only a matter of time before something big happens, something they can't contain, and things are only going to get worse. No one knows what is coming, there's no way to prepare for what lies ahead. All they can do is try to keep the supernaturals under control any way possible.
