Subspecies V: Bloodrise (DVD)

Stolen by crusaders on the night of his birth from his demon mother and vampire father, Radu grows up with no knowledge of his monstrous bloodline. Trained and exploited by a brotherhood of mystic monks to slay all enemies of the church, fate brings him back to his father's castle, armed with the monster-slaying Sword of Laertes, to destroy the vampire Vladislas and reclaim the Bloodstone.
