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.

Romaniello opens up to Imma and shows his true colors. Imma takes her mom home, but the apartment seems unfamiliar to her with its modern conveniences like a TV, and running water.

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.

Imma calls Romaniello in and tells him her version of the story.

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

Leila's story identified the killer but can't be used as evidence. Imma and Calogiuri go to the beach club to look for Vaccaro.

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.

Leila can barely open her eyes or speak, but she understands what Imma is asking her, and manages to tell her about what happened to Aida.

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.

Thanks to Imma and her team, Staffieri is arrested. Romaniello goes to Nunzia's house with Imma to ask forgiveness.

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 the eve of Ferragosto, the big August holiday. Imma has her mind on work, but in the midst of the dinner table chatter, she turns her attention to her daughter, Valentina, who is still not speaking to her.

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.

Imma convinces Nunzia to talk. And she has plenty to say. Imma and Calogiuri discuss the case as they go to the supermarket for groceries, since the next day, all the shops will be closed.

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.
