Plot
Businessman Costante Nicosia has married for wealth. He has recently inherited toothpaste factory and owns a basketball team. Nicosia is abusive to his employees and very superstitious. One day, a black cat crosses Nicosia's path, and he breaks a mirror in his apartment. Superstition demands that he persuade a virgin to urinate over the broken mirror to halt the tide of bad luck. He passes an old spinster who lives next door and mistakenly assumes she is a virgin.
Bowing to family pressure, Nicosia employs his loafing brother-in-law to the factory's menial post but fires him the following day after catching the man asleep on the job. That evening at a family gathering at his apartment, he is accosted by his in-laws, who try to shame him into giving the man his job back. Instead of acquiescing, Nicosia bursts into a tirade of rudeness against the singer's figure of his Great Aunt Maria. The old woman responds by uttering a curse. Nicosia dismisses her until she threatens to pour oil onto the floor; this bit of magical business makes Nicosia recant in a panic. Nicosia grovels for the curse to be lifted, and the old woman refuses to do so.
Days later, Nicosia is on a plane to Bucharest for a business conference. A man seated nearby introduces himself as Count Dragalescu and invites Nicosia to visit him at his castle. At the hotel, Nicosia discovers that the conference has been postponed, leaving him stranded for the weekend. Rather than spend the weekend in the hotel, Nicosia decides to call on the Count.
At the castle, Nicosia is greeted by Count Dragalescu when a group of revelers staggers down the staircase into the dining hall. The Count introduces his companions (three women and a man) to Nicosia, who is then sent to his room to prepare for dinner.
When Nicosia returns well dressed in a tuxedo, he finds himself overdressed for the occasion. Embarrassed, Nicosia sits down at the dinner table near a naked Count Dragalescu and his bevy of naked women. The evening gets even more debauched when Nicosia has too much to drink, disrobes, cavorts with the three nude women of the assembled throng, and then passes out cold. The next morning, he wakes up in his bed with the grinning Dragalescu lying next to him. The half-dressed Nicosia runs in horror from the castle and catches the first plane back to Italy.
Back in Italy, Nicosia fears having become a homosexual man. He goes to his physician Dr. Paluzzi, who suggests he should try making out with his mistress; should he be unable to do so, this would mean he has been "deflowered while drunk." However, this attempt to re-establish his heterosexuality fails because the tormented Nicosia feels compelled to bite her neck and suck her blood.
Disturbed, Nicosia calls on his Great Aunt Maria to beg her to remove the curse which, he assumes, is responsible for his homosexuality and blood craving. However, she claims that she had nothing to do with that. She recommends he visit the Magician of Noto in Sicily for help. Upon arriving at the Magician of Noto's residence, a desperate Nicosia sees that the magician is a fake, judging from his posture and tone of voice. But Nicosia accepts his advice: the curse on him will be lifted only if he re-hires his brother-in-law. The whole thing is actually a deliberate stunt organized by his in-laws for Nicosia's brother-in-law to recover his job. Returning home, Nicosia responds to his wife's sexual advances by plunging his fang-like teeth into her bare bottom during foreplay.
Over the next months, Nicosia adopts devil-may-care aggression; he re-fires his brother-in-law, visits prostitutes to satisfy his urge to bite, and isolates himself from family and friends. He eventually satiates his craving by setting up a blood bank at his factory site and compelling all employees to attend. Just as he seems to have surrendered to total cynicism, his wife arrives at the factory with a baby, his newborn son that was conceived Nicosia's vampiric phase. Rejoicing at his proof of his potency, Nicosia goes to hold his son, only to discover that the baby has fangs.
