Giandomenico Fracchia, Villaggio's "monstrously shy" character, is tasked to sell a piece of real estate in Transylvania, otherwise he'll lose his job. The customer is the obtusely nagging and prickly accountant Arturo Filini, who suffers from heavy nearsightedness and who doesn't realize that the manor he's interested in is actually Count Dracula's castle. Once on the spot Fracchia is terrified at the going-ons while Filini, in true Mister Magoo-style dismisses them as 'tricks' to dissuade him from the estate deal. Meanwhile a young and attractive vampire hunter (Isabella Ferrari), arrives, determined to avenge the death of his brother, who perished trying to rid the world of Dracula and his cohorts. The events turn even more farcical when Dracula's sister confesses her love for Fracchia to try to avoid being engaged to the Frankenstein Monster. In the end an ash-tipped umbrella seems to solve the situation but...was it all for real or just a horror-movie fueled nightmare??
