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.

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.

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

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

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

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.

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

Imma is back in the office and so is her talkative assistant, Diana. Imma's boss comes in with some papers. Who knows? Now that summer is almost over, maybe Imma will find some time to relax.

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

We begin a new episode, where Valentina is at school, learning about politics and toxic waste.

Imma goes to where the dead body of Nunzio Festa had been found. She has to deal with the local Carabinieri marshal, who is a bit of a bully. She and Calogiuri go to see the parents of the deceased.

Imma and Calogiuri rummage around in Nunzio's room, and Imma sees a photo: Nunzio's girlfriend. So they go to see her next after asking Nunzio's stepmother some questions.

Imma talks to Milena, without much success, but then she gets a phone call she has to deal with.
