Elena is at the fancy dinner, and is worried about Giuseppe, but at the same time, she is fascinated by the after-dinner entertainment. Giorgio is taking advantage of Giuseppe's absence. Meanwhile, Giuseppe is working against the clock, realizing that his patient, from one of the poorest and most dangerous neighborhoods of Naples, has a terrible disease.

After being left by the taxi driver, Giuseppe goes in search of the Esposito home. The taxi driver was right about the danger. Meanwhile, Giorgio shows up at the dinner and greets Elena and her father.

Giorgio is getting settled in his new office and gets an unexpected and unwelcome visitor. Giuseppe has a big evening ahead of him with Elena and her father, but he gets some news he has to take care of and is delayed.

Sister Helga and Moscati give the patient a bath and talk about how medicine is nothing without love. Moscati has some unorthodox teaching methods, as well as some novel "therapy" for his patients.

Moscati discovers what Aniello died of and feels profoundly aggrieved and powerless. He seems to have doubts about his role as a doctor.

Moscati can't find Aniello in the hospital and discovers he had run off. Moscati goes out looking for him.

Giorgio goes to see Cloe perform, but afterwards, he makes an important decision. Giuseppe finally finds Aniello, who is not doing well at all.

Both Giuseppe and Giorgio take the exam for the available position. They each have to diagnose a patient and the examination board isn't kind to either of them.

Moscati risks his life to save some of the patients from the hospital. It took courage and patience.

In 1906 Vesuvius erupted, its worst eruption of the entire 20th century. Torre del Greco, a town near Vesuvius, was particularly affected. Buildings collapsed, sick people were trapped inside the hospitals, and Giuseppe and Giorgio rushed there to help out.
