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

To evade inspections, Michele suggests to Riccardo to 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 makes a mistake and finds a man who makes a scene. Meanwhile, a school group arrives at the Nido asking for Eleonora.

Eleonora had forgotten that her teacher friend would bring the kids on a field trip to the Nest and asks Chiara for help to welcome 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 visiting kids go around the Nido asking questions and exploring the place when they find the hole the workers are working on. At that point, Eleonora asks her friend to take the kids away.

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