Adriano tells Grazia his ideas for a new kind of city. Back at the factory, cuts are being made, and there is talk of layoffs. We also discover an ironic fact about Adriano.

There is more to tell about the incredible, huge cistern in the center of Matera. With this, the episode concludes, with an invitation to join in the next journey of discovery.

As luck would have it, Adriano has a chance encounter with a young woman who has a problem he is uniquely capable of solving. Teresa and her daughter Maria have an unexpected caller.

In Matera, various epochs shake hands, as Alberto Angela put it. Matera continues to amaze us with what's hidden underneath the piazza of the Baroque quarter: Il Piano.

Even though he is no longer leading the company, Adriano is as active as ever. Events come together that motivate him to put his theories into practice.

Living conditions were so different at the time of the cave dwellings. Imagine having a mule and rabbits running around the house! The government eventually put a stop to this type of dwelling, and much was gained, but much was lost. On the other hand, people had to live somewhere. The Civita, the oldest part of Matera, filled up quickly around the imposing cathedral, and there was no more room for building houses.

Adriano decides to leave running the factory to Marcello and goes off on his own to work on his other projects. But country roads are dangerous in the pouring rain...

We see the inside of house built into the rock. It is fascinating to learn how families coped with the problems of water, humidity, and cramped quarters.

Adriano is very happy with how things have been going for the new Olivetti portable typewriter, but his siblings and partners in the business are not so happy. For one thing, they don't like not seeing any of the profits.

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

Teresa and Libero go to the movies together, and things seem great. But Libero has something important to tell her, something she had no idea about.

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.

The "Lettera 22" portable typewriter is selling well, although Mauro isn't in complete agreement about the price. Libero and Teresa make some plans, and Mister Dalmasso comes around again.

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.

Adriano shows Karen Bates around the new building and she writes her report. The new portable typewriter designed by Libero is finally ready.
