Mario has invited his friends from the co-op to lunch, where he tries to work out a deal with them to clean up the property. Eleonora sees Chiara putting something in her top drawer and is curious.

Having heard about the money from Chiara, Eleonora goes to see Michele to confront him on the issue. She feels he is leading Chiara astray.

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.

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.

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.

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.

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.

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.

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.

While the workers begin to dig, the members of the Nest are busy moving the young people out of the area. Some members, however, are in full meltdown.

Mario is trying to teach Domenico how to play chess, but since it's a losing battle, he asks him what he thinks about his responsibility towards the Nest. Meanwhile, the workers come up against something strange while digging.

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.

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.

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.

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.
