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.

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 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.

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.

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.
