The film tells the story of the Hungarian Countess Elizabeth from an ancient family Bathory, niece of the king. According to the legend and evidence Palatine Gyorgy Thurzo, she killed a lot of young girls to bathe in their blood for rejuvenation. But there is another version, which is described in the film. According to an alternative view, the majority of the evidence provided by the Palatine, were forged. Gyorgy was interested in her custody, to take away a large amount of land that eventually became his property. In any case, now the Countess Bathory is in the Guinness Book of Records as the most popular serial killer.
