Mr. and Mrs. Dracula take up residence close to a sanatorium "For The Disturbed." At the sanatorium there is a jolly assortment of characters including the Odd Sisters, who can never complete a full sentence, Mrs. Half-Nelson, who knits with invisible needles and yarn, and Lucy, who wears necklaces of garlic to ward off evil. Enter vampire hunter Van Helsing, who is determined to discover the villain's identity. It isn't easy with people appearing and disappearing, poisoned food and a howling wolfman. Add to this a procession of hilarious chases and you have a delightful comedy.
