A former priest has become bored to the point of impotence by the easy availability of beautiful women. He misses the shame of the priesthood which made sex more enjoyable, and this leads to his strange fascination with photographing asses. He gets involved with a sexy married woman, but he is more interested in her virginal maid.

Paulina, sister of Napoleon I, is married to Camillo Borghese, presented as a helpless coward. She is eager to offer herself to all the young people that propose to her, and performs naked in front of the Roman people flocking to the walls of Villa Borghese, which she turned into a private residence. She also poses half naked for the famous statue of Canova, who is also presented as a effeminate and scoundrel. When her reputation as a depraved spreads, on the advice of the Pope, she is segregated away from all the men. when the French troops deport from Rome the Pope and the cardinals as well, Paulina sees prostitution as the only way to find herself some "fresh meat". Finally after seven years villa Borghese is reopened to the public, as Paulina goes back to Paris, to the great relief of the Roman people and the clerical circles.
