In Rome in 1959, Agostino is the ferocious new Secretary-General of the Italian branch of the worldwide International Organization for Public Morality. A teetotal bachelor, he attacks with vigour public manifestations of sexual immorality. Neither bribes nor female charms deflect him from his crusade against lewdness in films and night clubs. So devoted is he that the aristocratic President of the Organisation even considers he might be a husband for his so far unmarried 29-year-old daughter.
But both President and Secretary-General also have private lives. After Agostino denounces a night club to the police and it is closed, the mistress of the owner befriends the widowed President and introduces him to an exclusive brothel. Meanwhile, Agostino is representing Italy at the annual congress of the Organisation in Munich and, after hours, recruits a stripper to work in Rome. Visiting a theatrical agent, in reality a white slaver, he also recruits a troupe of African dancers, all illegal immigrants. Integral to the deal is that after each show they must entertain private clients.
The police have been closing in on Agostino, who has a long history, and he is arrested. When the inspector says the charge is white slaving, he protests that the artistes were black.
