The Williams clan is a family just like any other, but they also have a secret. They are a family of werewolves and interact with other supernatural beings every day, sometimes going to great lengths to keep their existence a secret. When a rogue werewolf leaves a violent, bloody wake in their territory, the family must set aside their differences to stop this monster before the trail of bodies uncovers the truth about them and the entire supernatural community to the rest of the world.
