As Franco Migliacci wakes up after his hangover, he sees the poster he bought of Chagall's famous blue painting, and starts writing some lyrics. Later on he gets together with Mimmo, and has to be cajoled into showing him what he has written.

Three months have passed, and Mimmo and Riccardo are still trying to find the right lyrics for the song. Their frustration comes to the surface and the song risks going up in smoke.

In the middle of the night, Mimmo finally comes up with the refrain to the song that would become famous the world over. He can't curb his enthusiasm and calls Franco and Gramitto, even though it's three in the morning.

When Franca comes home after her day on set, she finds Mimmo asleep on the couch surrounded by sheets of music paper. She has some news for him. He goes to Milan to meet with Gramitto who has always been skeptical about the new song ever taking off.

It's New Year's Eve and Mimmo and Franca celebrate with friends. As promised, Mimmo gets some concert clothes from the Sanremo festival. And then, the big day arrives and Domenico finds himself in the midst of already famous artists.

Franco Migliaccio is filled with pessimism and Johnny Dorelli is filled with fear, but Mimmo is feeling very sure of himself at the Sanremo Festival.

Mimmo and Franca have a relaxing moment by the sea. Franca has some important news for him.

The big night arrives and we, along with so many watching him on black and white TV, finally hear the song in Modugno's performance at Sanremo. It was a moment of great pride and optimism for Italy.

The winner of Sanremo is announced, and the news travels fast. The winning song makes Italians feel optimistic after the terrible war and postwar periods.

Domenico Modugno goes to New York City, where he sees his song has taken over. It made history all over the world.
