In the
Sicilian town of Agramonte, Ferdinando Cefalù, a 37-year-old impoverished nobleman, has been married for 12 years to Rosalia, a devoted wife he no longer loves. He is in love with his 16-year-old cousin Angela, whom he sees only during the summer because her family sends her away to Catholic school in the city. Besides his wife, he shares his life with his elderly parents, his sister, and her fiancé, a funeral director. The family share their once stately palace with his uncles, who are slowly but surely eating away the remainders of their once-rich estate. Aware that
divorce is illegal, Ferdinando fantasizes about killing Rosalia, such as by throwing her into a boiling cauldron, sending her into space in a rocket, or drowning her in quicksand. After a chance encounter with Angela during a family trip, he discovers that she shares his feelings. Inspired by a local story of a woman who killed her husband in a fit of jealousy, Ferdinando resolves to lead his wife into having an affair so that he can catch her
in flagrante delicto, murder her, and receive a light sentence for committing an
honor killing. He first needs to find a suitable lover for his wife, whom he finds in the local priest's godson, Carmelo Patanè, a painter who has had feelings for Rosalia for years. For a time, he was presumed killed during
World War II. Ferdinando also procures the State Prosecutor's friendship with a small favor. The final stage of his plan is to arrange for Carmelo's constant presence in his house, which he achieves by feigning interest in having his palace frescoes restored. Carmelo is timid with Rosalia, and she is initially committed to conjugal fidelity. Ferdinando tapes their private conversations and has to ward off the maid Sisina's infatuation with Carmelo. After Carmelo makes a pass at Sisina, she tells the priest, Carmelo's godfather, in
confession, who informs her that Carmelo is married with three children. She relays that information to Ferdinando. Rosalia and Carmelo finally give in to their passion, but the tape of their conversation runs out just as they are arranging their next meeting. All Ferdinando knows is that it will take place the next evening. Rosalia feigns a headache and remains home while the rest of the family goes to the cinema to see the local première of
La Dolce Vita, a film so scandalous that no one wants to miss it. Ferdinando sneaks out of the cinema and returns home, arriving just in time to see Rosalia leaving for the train station. He retrieves his gun to kill her, but arrives at the station just after their train departs. He revisits his plan and the
Criminal Code. It defines a crime of passion as executed in the heat of the moment or in defense of one's honor, so he embraces the role of a cuckold. All along, Angela has been writing Ferdinando to assure him of her undying love for him. Her last letter is misdelivered to her father, who dies of a heart attack upon reading it. At the funeral, Ferdinando is approached by Mrs. Patanè, who demands to know what he will do about their situation. After he responds noncommittally, she spits in his face in front of the entire town, which gives him what he needs: an open insult to the family's honor due to his wife's elopement. The local
Mafia boss offers to find the lovers within 24 hours, which he does. As Ferdinando goes to the lovers' hideout, he hears Mrs. Patanè kill Carmelo. He follows suit and kills Rosalia. At his trial, he is defended by the State Prosecutor, who blames the incident on Ferdinando's father, declaring that he failed to give his son enough love when raising him as a boy. Ferdinando is released from prison after three years and returns to Agramonte, where he finally marries Angela. Months later, Ferdinando and Angela are happily sailing at sea. As they kiss, Angela seductively rubs her foot against that of the young helmsman piloting the boat. ==Cast==
