Professor Von Helsing has done the world a favor by driving a stake through the heart of Count Dracula and thus destroying him. For his trouble, Scotland Yard charges him with murder. Dr. Jeffrey Garth, a psychiatrist, may be able to act as an attorney and defend him in court. But Garth finds he has his own troubles when the Countess Marya Zaleska seeks his help. She wants to be released from her desire to drink the blood of the living. She steals the corpse of her father, Count Dracula, and burns it ritually; but she still wants blood. She'll do anything to free herself of this curse, including kidnapping the baron's daughter who is Dr. Garth's assistant, and thwarting the hopes of her sinister manservant, Sandor.
