In 19th-century middle Europe, orphaned teenage twins Maria and Frieda go live with their uncle Gustav Weil, who heads the Brotherhood, a vigilante group trying to stamp out vampirism. But the real threat lies with Count Karnstein, and it is not long before Frieda finds herself drawn to the Count's sinister castle.
