His father has sent him to hire Samantha, a bodyguard, under the pretense of protecting the family against an unknown enemy, most likely werewolves. Both are in the dark regarding his true purpose - creating a master race of vampires that will be able to once and for all destroy the werewolves.
Disbelieving that she is the key to the Master race, and unwilling to be a pawn, Samantha becomes the hunted. When the vampires she has vowed to kill capture her, Samantha escapes only to get kidnapped by werewolves. Finding herself in a battle for her own life, she quickly discovers that the only way to save herself is to actually unite both factions to fight an even greater enemy!
