Their marriage is not welcomed by Aurelio's brother-in-law Enrico and his wife Sonia. Enrico suspects that Arianna marries Aurelio for his fortune. Despite not on good terms with Arianna, Enrico has an incestuous relationship with Arianna's bitchy daughter Carlotta. Carlotta desires for stepfather Aurelio and successfully seduces him to her bed. Meanwhile Enrico plots to blackmail Arianna by paying young man Mario to have a homosexual relationship with Arianna's gay son Gustavo. Upon learning of her son's homosexual tendency, Arianna tries to change Gustavo's sexual preferences by making love to him to let him experience sexual pleasures with a woman. However, Gustavo's gay tendency remains strong and he is enticed to go back to Mario. Acting on Enrico's plan, Mario forces Gustavo to arrange for him (Mario) to have sex with Arianna. Arianna sleeps with Mario for the sake of her son Gustavo. Arianna's world falls apart when Enrico threatens to expose her infidelity to husband Aurelio.
