Berardi is back in the Rome office and there's a celebration. But since there's also a dead person at the Colosseum, the celebration comes to an abrupt end and Berardi and Torre rush to the scene of the crime. The class trip also comes to an abrupt end.

After two years, Camilla and Gaetano meet up again at the scene where a woman had been found dead. They fall into their usual habit of discussing the crime, as if not a day had passed.

Gaetano receives a phone call and when it ends, he finds himself obliged to tell Camilla that it was from a journalist he had met in Prague. Back at school, Camilla wants to know more about the centurion, while Renzo is dealing with a problem at his studio.

Berardi is gathering information about the victim. Ferrari identified a report about a missing American girl and Berardi goes to see her sister, who reported it. Meanwhile, Camilla's house has gotten flooded and Renzo is very angry.

While the investigations continue, Renzo has an unpleasant surprise that undermines his peace of mind as a husband, and even a competition he must participate in doesn't give him peace.

At school, Alex and Aiello are arguing because Aiello wants Alex to delete some photos from his phone, but Alex doesn't want to. With Camilla's arrival in class, the argument calms down, but the teacher would like to know why Aiello got so upset.

Gaetano asks Camilla for help in identifying the centurion who found the girl's body. At home, Renzo is working on the competition and has a surprising conversation with his colleagues.

Renzo is at home with Livietta and he is helping her with a project for school. Camilla goes to help Gaetano with the recognition of the centurion, but she will also need Gaetano's help later.

In the car, Camilla and Gaetano talk about commitment in relationships and marriages. When they arrive at Camilla's house, they unload the water heater together, when Renzo sees them.

People seem to think Alberto is a bit nuts. He's about to go on live TV, and people around him hope he doesn't botch it. The name of the TV show is Non è mai troppo tardi (it's never too late). What's implied in the title is that it's never to late to learn to read and write. In Italian, a person who never learned to read or write is called analfabeta.

In Italy, at least in the past, the process of distributing teaching jobs was a real jungle, as you will see. The list, assembled by a complicated point system, involving test scores, experience, seniority, etc, was what would determine whether an aspiring teacher would have a job that year or not. Alberto Manzi knows he is qualified, but gets an unpleasant surprise at the education office.

Manzi goes to the reform school for his first day of teaching and finds out all the things he will or won't be able to do.

Will Alberto Manzi be up to the task of dealing with these rough, incarcerated boys? On his off-hours, Alberto goes to see the parish priest about a missing person.

Alberto's friend, Eugenio, is ready to call it quits when it comes to teaching. Alberto is convinced that kids are the future, but even though he made some headway with the kids at the reformatory his first day, there are still huge obstacles.

Manzi isn't getting anywhere with the kids at the reformatory. He talks to the director, and then goes to the Board of Education, too, to complain.
