Loosely based on the video game of the same name, the film centers on the character of Rayne (Kristanna Loken), an unholy breed of human and vampire called a Dhampir. Dhampir are unaffected by crucifixes and do not thirst for human blood. She is the daughter of the Vampire King Kagan (Ben Kingsley) who has gathered an army of thralls, both vampire and human, in order to annihilate the human race. She was conceived when Kagan raped her mother, and she later witnessed him killing her.
Sebastian (Matthew Davis), Vladimir (Michael Madsen), and Katarin (Michelle Rodriguez) are three members of the Brimstone Society, who fight vampires. They hear of a carnival freak who may be a Dhampir, Vladimir plans to recruit her in order to kill Kagan. Kagan is also hunting for her fearing she will interfere with his plans. Rayne escapes captivity at the carnival. On the road she encounters and saves a family being attacked by vampires. A fortune teller reveals to Rayne that Kagan has become the most powerful vampire in the land and resides in a well protected castle. She tells Rayne that Kagan seeks an ancient talisman, a mystical eye, and if she finds it, it would allow her to gain an audience with Kagan. Rayne sets out to the monastery to find it.
Rayne shelters for the night at the monastery and later sneaks away to where the talisman is guarded by a hammer-wielding deformed monk. The talisman is protected by further booby traps and when Rayne lifts it from the pedestal the chamber floods with holy water. As Rayne hangs from the ceiling to avoid the water the talisman falls from the box but she catches the eye ball. Examining it closely the eye magically becomes absorbed into her own eye and when she falls into the water she is somehow unaffected by it.
When she leaves the chamber the monks explain the artifact is one of three body parts which came from an ancient vampire called Belial who had found a way to overcome the weaknesses of a vampire. The eye overcomes holy water; the rib overcomes the cross; and the heart overcomes sunlight. The parts have been hidden across the lands. As Kagan wants all these parts, it becomes the heroes' mission to stop him.
Rayne is brought to the headquarters of the Brimstone society and they agree to work together to kill Kagan. Katarin does not trust Rayne and betrays Brimstone to her father Elrich who has fallen in league with Kagan, but seeks to betray him and gain power for himself. The location of the heart talisman is known to Katarin as her grandfather hid it in water filled caves. She seeks it out but Rayne fights and kills her for it. With the talisman Rayne attempts to gain an audience before Kagan, but he takes the heart and throws her in the dungeon. He plans to extract the eye as part of a ritual. He realizes too late Rayne had only given him an empty box and not the heart.
Sebastian and Vladmir intervene battling Kagan and his minions but both are fatally wounded leaving Rayne in a final battle against Kagan. As Sebastian dies he fires a final bolt from his crossbow but Kagan is too quick and is able to catch it, but Rayne is able to summon her last reserves of strength and plunge the bolt into his heart. The battle ended Rayne seats herself in Kagan's throne and remembers with a smile, then finally leaves the castle and rides off into the distance.
