Dampyr

Set during the Balkan War in the early 1990s, the film tells the story of Harlan Draka who, haunted by horrific nightmares, wanders the countryside, making money pretending to be a Dampyr - half human / half vampire - who liberates villages from what the inhabitants believe to be vampires. But when he is summoned by soldiers attacked by real vampires, Harlan discovers the horrible truth: his nightmares are real!
