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 Nana (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.
