Filled with torture chambers and mantraps, the Transylvanian castle of Baroness Catali has lain empty for fifteen years.  When American actress Betty Williams, heir to the manor, arrives to claim her inheritance, she learns of the gruesome fate that befell her grandmother—found murdered in her bead, naked, with her neck punctured.  As the actress settles in, the undead Baroness emerges from her tomb with an unquenchable thirst for blood.  Striking first at the nearby seminary, the vampires devours the men of the town.
