a polluted estuary when they meet up with another couple, Max and Linda, and together they drive to a small riverside shack at Porto Corsini where they meet Emilia. They spend time in the shack engaged in trivial small talk filled with jokes, role-playing, and sexual innuendo. Giuliana seems to find temporary solace in these mindless distractions. In a dense fog, a mysterious ship docks directly outside their shack. During their conversations, Corrado and Giuliana have grown closer, and he shows interest and sympathy for her. When a doctor arrives to board the ship, Giuliana, seeing that the ship is now quarantined due to an infectious disease, rushes off in a state of panic almost driving off the pier. Sometime later, Ugo leaves on a business trip, and Giuliana spends more time with Corrado, revealing more about her anxieties. One day, her son becomes suddenly paralyzed from the waist down. Fearing he has contracted polio, Giuliana tries to comfort him with a story about a young girl who lives on an island and swims off a beach at an isolated cove. The girl is at home with her surroundings, but after a mysterious sailing ship approaches offshore, all the rocks of the cove seem to come alive and sing to her in one voice. Soon after, Giuliana discovers to her shock that Valerio was only pretending to be paralyzed. Unable to imagine why her son would do such a cruel thing, Giuliana's sense of loneliness and isolation returns. Desperate to end her inner turmoil, Giuliana goes to Corrado's room. Giuliana is distraught and begins to disrobe. Initially resisting Corrado's advances, the two make love in his bed. The intimacy, however, does little to relieve Giuliana's sense of isolation. Corrado drives Giuliana to her empty shop, where she remarks that there is something "awful" about reality. Later, Giuliana wanders to a dockside ship where she meets a foreign sailor and asks if the ship takes passengers. She tries to communicate her feelings to him, but he cannot understand her words. Acknowledging the reality of her isolation, she says, "We are all separate." Later in the daytime, Giuliana is walking with her son near her husband's plant. Valerio notices a nearby smokestack emitting poisonous yellow smoke and wonders if birds are being killed by the toxic emissions. Giuliana tells him that the birds have learned not to fly near the smoke. Cast
