Michele is looking for a work of art to give as an important gift. Meanwhile, at the Nest, they continue to dig and are finally about to discover what lies beneath the slab.

The school kids go around the Nest asking questions and exploring the place when they find the hole where the workers are digging. At that point, Eleonora asks her friend to take the kids away.

Riccardo tries to approach and talk to Menicucci twice, even asking Michele for advice on how to do it, but he doesn't succeed. At the Nido, the visiting class doesn't seem very inclined to listen to the history of the place.

Eleonora had forgotten that her teacher friend was going to bring her students on a field trip to the Nest. She has to go to work and asks Chiara for help in welcoming them. Meanwhile, the police arrive while Michele is on the phone.

Riccardo is trying to give the bribe to the person indicated by Michele but gets it wrong. Meanwhile, a school group arrives at the Nido asking for Eleonora.

In an attempt to kill himself, Mario jumps out of the window, ending up in the emergency room with a contusion. While Michele tries to break free from Iolde's advances, Riccardo calls to say that Menicucci has arrived.

To evade inspections, Michele suggests that Riccardo bribe a health department official with a thousand Euros and have him call ARPA to block the soil inspection at the Nido. Riccardo, although uncomfortable, goes to the health department offices.

While the workers are digging, they find a metal plate that's hiding something and it turns out that Mario actually knew about it and feels guilty. Before proceeding to remove the metal plate, they need to obtain a special tool but the important thing is for nobody else to know what's happening.

Mario, wanting to be helpful, would like to block the entrance to prevent the inspectors from entering, but Michele manages to convince him that it's not a good idea. The workers have formed a strange idea about the place.

In the area of the Nest targeted by the team, work is being done to eliminate the contaminated part. Riccardo urges everyone to take precautions and sleep with open windows if they cannot spend the night elsewhere.

The workers Michele had called found that the pollution is only on a part of the land, but to clean it up they need the whole night and some help to give them energy. Iolde is trying to help Michele out by lending him her phone.

While everyone is sitting around the table, a phone call comes from the environmental agency saying they will come the next day. There is some panic. Michele keeps his cool.

Michele is at the Nest, but he's still under house arrest, so he has to do certain things because he's obligated to. Indeed, breakfast time arrives in the common room.

The two night workers take the cash and want to look around to take some measurements. Riccardo is shocked to see all the cash and asks Eleonora about it. Iolde is waiting for Michele, ready to have a glass of wine with him.

Mario apologizes to the group and they decide to take up Michele's original solution, the night business. Iolde seems eager to develop romantic relations with Michele and comes on a little strong.
