Blood of Dracula's Castle

Count Dracula (Alexander D'Arcy) and his vampire wife (Paula Raymond) are occupying Falcon Rock Castle in modern-day Arizona, hiding behind the identities of the Count and Countess Townsend. When the castle's owner dies, the property passes on to a photographer named Glen Cannon, and Glen has decided to live there himself with his fiancée Liz. He drives out to the castle to inform the Townsends that they will have to move out. But his car breaks down when he gets there, and he and Liz are forced to spend the night with the Townsends.
