In the piazza, Giuseppe discusses the war with some colleagues. He then runs into an old acquaintance. Later, in the lab, he talks about science and faith with his professor friend.

When Moscati arrives home, he has a huge surprise waiting for him: an endless stream of poor people. At the hospital, Sister Helga catches Arcangelo with a nurse and is furious.

Arcangelo and Sister Helga don't like each other much, but they have to work together to save the patient. At home, at lunch, Giuseppe has a strange feeling and rushes off.

Giuseppe's colleagues want to get Giuseppe away from the hospital because he makes too much "trouble." Giorgio has a suggestion for that.

Elena explains her health problem to Giuseppe and they also clarify some personal things. Giuseppe then takes her to a special place in the city.

Elena seems charmed by the orphans and Giuseppe explains to her that love has many pathways. At home, it becomes clear that Nina and Giuseppe have grave financial difficulties. He won't give up seeing patients, but comes up with an idea.

Pasquale is a bit heavy-handed in his attempt to manage the collecting of money from the more well-to-do patients and Giuseppe has to step in. He and Nina sell off many of their possessions and Nina has a hard time of it. At the end of a long day, Giuseppe gets a surprise visit

Elena goes to see Giuseppe together with little Antonio. She notices right away that the apartment is empty. At the hospital, one of Mussolini's federal agents is visiting and gives Moscati some troubling news.

Giuseppe goes to see Giorgio to see if he has the power to save the hospital from the new "reforms," but Giorgio has other priorities and rebuffs him.

Giuseppe's health is failing, but he won't accept Arcangelo and Nina's advice to get some rest. He seems to be well aware of his true condition and writes a letter to his loved ones. Elena brings Antonio home.

Even though Giuseppe's health is failing, he goes to see the needy in the poorest sections of Naples. Even when he gets home for dinner, the patients keep coming. He doesn't turn them away.

Giorgio is on his way home, but changes his mind and goes to Piazza del Gesù.

Giuseppe is very happy that Giorgio came to see him. The two friends have an important and sincere conversation.

Alberto Angela, well-known presenter of historical TV documentaries, takes us on a journey to discover some of the "wonders" — both man-made and natural — of this "treasure peninsula" called Italy. The journey begins at the Royal Palace in Caserta.

It's hard to fathom the scale of this royal palace. We learn how many workers it took and how long it took to build. The grand staircase is of amazing dimensions, and, when seen from the top, our host seems like a small dot at the bottom of it.

We visit the magnificent, immense Throne Room, with its small but elegant throne, and vaulted, frescoed ceiling.

Alberto Angela takes us from the public throne room to the private chambers of the Royal Palace. In order to obtain the desired wall coverings, a whole complex was built for manufacturing silk. It's still operating today. Incredibile!

The narrator makes us aware of the vast number of people necessary to run the Palace. We visit the most intimate place in the Palace: the queen's dressing room and bathroom. It is fascinating to learn all the ways in which it was outfitted to both pamper and protect the queen.

If we thought the interior of the Royal Palace of Caserta was amazing, we should get ready for even more amazement as we go outside and see the spectacular park — a true capolavoro (masterpiece) — which Luigi Vanvitelli, architect and engineer, designed, giving water the starring role.

Exploring the gardens further, we come upon a grotto, as well as what looks like an ancient Roman site, replete with original statues. It was all part of Vanvitelli's plan.

We leave the Royal Palace of Caserta and head towards Cilento in Campania where there is a huge Benedictine monastery. When we see the term convento, we might assume it is a convent for nuns, but in Italian, un convento can be a religious community for either monks or nuns (or both).

Alberto Angela us takes back in time, to a city that came about in a totally different way: splendid Matera in Basilicata. It's definitely worth a trip.

Matera is all about caves and grottoes. There were many natural caves that were expanded to be used as dwellings and churches, and other man-made grottoes as well.

We enter a fascinating church carved right into the rock: the Church of the Madonna di Idris. There are some surprising discoveries awaiting us.
