A 19th century vampire stalks a more powerful vampire lord in his quest to gain revenge over the death of his mistress. In his search for the vampire lord in Eastern Europe he kills many of his servants and fellow vampires while cursing another to vampirism as well.

Stolen by crusaders on the night of his birth, Radu (Anders Hove) has no knowledge of his bloodline: his mother is a demon; his father is a vampire. Trained and exploited by a brotherhood of mystic monks to slay all enemies of the church, fate brings him back one night to the castle of his father, armed with the monster-slaying Sword of Laertes, to destroy the vampire Vladislas and reclaim a holy relic: The Bloodstone. The events of that night turn Radu from a noble man into a vampire with no master, setting him on a centuries-long quest for sustenance, and companionship, for the treacherous one who stole him from the sun, and for the Bloodstone he hopes will bring him peace.
