In 19th century middle-Europe, orphaned teenage twins Maria and Frieda move in with their uncle Gustav Weil, who leads a vigilante group fighting vampirism. However, their methods only lead to chaos and fear among the population. Meanwhile, a more sinister threat emerges in the form of Count Karnstein, and Frieda's affinity for his castle sets her apart from her identical twin sister.
