Count Dracula (Carradine) arrives at the castle home of Dr. Franz Edlemann (Onslow Stevens). The Count, who introduces himself as "Baron Latos", explains that he has come to Visaria to find a cure for his vampirism. Dr. Edlemann agrees to help. Together with his assistants, Milizia (Martha O'Driscoll) and the hunchbacked Nina (Poni Adams), he has been working on a mysterious plant, the clavaria formosa, whose spores have the ability to reshape bone. Edlemann explains that he thinks vampirism can be cured by a series of blood transfusions. Dracula agrees to this, and Edlemann uses his own blood for the transfusions. Dracula has his coffin placed in the castle basement.
