Aramızda Yaşıyorlar. Bizimle Besleniyorlar. Biri öldürmek diğeri ise toplumla barışık yaşamak üzere iki farklı gruba ayrılmış kurt adamlar aniden aydan gelen bir etkiyle çağlar öncesinde kalmış bir kehanetin etkisi altına girer. Her iki tarafında kaderini ellerinde bulunduran yarı insan yarı kurtadam kanı taşıyan 13 yaşındaki genç Timothy ise yaşayacağı dönüşümden habersiz olarak 13. yaşgününü kutlamaya hazırlanmaktadır.

Two packs of werewolves, divided by principles, are signaled by the moon of the coming of an ancient prophecy. Timothy is a young boy who is approaching his 13th birthday. He is unaware this marks the time of his transformation. Timothy has been raised by his mother Rachel, his grandmother, his Uncle Jonas, his cousin Katherine and her boyfriend, Adam. Rachel and Timothy have been unaware that the rest of the family are good werewolves and have been guarding Timothy since birth. They know that Timothy is a half blood, and will control the destiny of the family. 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 prepared to kill to preserve their way of life.
