Two packs of werewolves, divided by principles, are signaled by the moon of the coming of an ancient prophecy. A young boy named Timothy (Matthew Knight) approaches his 13th birthday, unaware this marks the time of his transformation. Timothy has been raised by his grandmother (Barbara Gordon), his mother Rachel (Rhona Mitra), his Uncle Jonas (Elias Koteas), his cousin Katherine (Sarah Carter) and Katherine's boyfriend, Adam (Shawn Roberts). His father is said to be dead. Rachel and Timothy have been unaware that the rest of the family are "good" werewolves who have guarded Timothy and his secret since birth. They know that Timothy is a "half-blood" who is prophesied to end the curse. But they also know that Timothy's power will put him in danger, for there are other werewolves that revel and embrace their blood-lust and are bent on finding and killing the boy.
