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.

Alberto gets a friend to drive him to where Ida teaches. He recognizes her right away as the kids come out of the school.

Alberto sleeps on the park bench across from Ida's apartment and then goes to work at the prison, where, once again, it's an uphill battle.
