Ferdinando Cefalù is desperate to marry his cousin, Angela, but he is married to Rosalia and divorce is illegal in Italy. To get around the law, he tries to trick his wife into having an affair so he can catch her and murder her, as he knows he would be given a light sentence for killing an adulterous woman. He persuades a painter to lure his wife into an affair, but Rosalia proves to be more faithful than he expected.

An anthology presents three storylines, all set in the Italian town of Treviso: A husband pretends to be impotent as a cover for having an affair; a bank clerk abandons his wife for his mistress, but the rest of the town's husbands become jealous and unite to conspire against them; and local men all seduce a promiscuous young woman, but when her father eventually reveals that she is underage, they all face prosecution for statutory rape.

The film presents the tale of Agnese Ascalone, daughter of prominent miner Vincenzo Ascalone, and takes place in a small town in Sicily. Agnese is seduced by her sister Matilde's fiancé, and has a tryst with him for which she confesses and tries to repent, only to be discovered by her mother and father.
