Bollenti spiriti (1981)

Count Giovanni degli Uberti is a nobleman on the verge of financial ruin; none of his business ideas has succeeded, and he is up to his neck in debt. His lawyer no longer knows how to save him from the creditors who want to take all his property. But then a stroke of luck comes his way: he has inherited a magnificent castle from his uncle Ubezio, and a Swiss real estate company is ready to pay him 2 billion lire to turn it into a hotel. All his problems seem to be solved, but the count discovers that he is not the only heir: the nurse who cared for his uncle in his final days was left 10% of the castle. If he cannot get his hands on that 10%, he will not be able to sell the castle to the Swiss real estate company. What is more, the castle is haunted by the ghost of Guiscardo, his ancestor, who was cursed to wander its rooms until he manages to make love to a woman. As if that were not enough, the wealthy Swiss real estate developer who wants to buy the castle is also the husband of Giovanni’s mistress: if he recognizes him, the deal is off.
