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 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, 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.
