Luca and Giulia are finally alone, in a car, at night, in a typical spot for lovers. Hmm...

Alessio and Martina, while working on the renovations of the beach club, start fooling around and making faces at each other. They're clearly having fun until Alessio goes one step further...

La ladra (The Thief) is a television series starring Veronica Pivetti, who plays Eva Marsiglia, a high level chef. But that's not all she does!

After a fruitless search in the rain, Luca and Brigadiere head home, but all of a sudden the dog starts sniffing around a hunter's shack, and sure enough, Luca discovers Marcuccio hiding inside, but the big man is not talking. And if that weren't enough, Manara's boss continues to put pressure on him and his team to bring in the perpetrator.

Alessio invites everyone he knows to the party at the Serenella beach club, and asks Martina to invite her friends, too, but she's not thrilled about that...

Marcuccio has gotten hungry, and so he's gone to see the only person he could trust, Lara's zia Caterina. But by the time anyone could come to help her, he'd disappeared again, leaving his jacket behind. Lara's dog, Brigadiere, gets a good whiff and goes off with Luca to look for Marcuccio. A storm has come up, making things more difficult.

Alessio has a very creative idea for saving the beach club. Tonino is skeptical, but gradually warms to the idea.

Lara and Luca go to interrogate a suspect whose only alibi for the night of the murder depends on Marcuccio, who is still missing. Meanwhile, Giulia intercepts a cryptic phone call.

Alessio is back at the beach club and shares a bed with Tonino's daughter, Martina. Once again he goes to the train station to meet up with his friends in Amsterdam...

Amidst murder and insomnia, Manara is attempting to eat his croissant during the autopsy in the morgue. And Ginevra... well, she has an infallible solution to help him get back to normal.

Anna and Marika tell us the story of Rosina, who in the midst of deception and intrigue, ends up getting married. But to whom? The one she loves, or the one who wants her at all costs?

The police intercept a phone call between Marcuccio and his mother, but it's too short to trace. Marcuccio recites the first line of Leopardi's most famous poem, "L'infinito" [The Infinite] to his mother. Giulia spends the night at Lara's and they watch the movie of the famous party. The next day Lara has some interesting news for Manara, from both Giulia and from her aunt!

Lara and Giulia have some catching up to do, but how candid are they being with each other? Do we detect a bit of jealousy? Meanwhile Commissioner Manara has to deal with both Romei, the chicken guy, and his buxom, brassy wife, who keeps trying to catch Luca's eye.

Alessio discovers why Tonino was so upset. The beach club is in danger of being demolished.

The arrival of Giulia Chiamparini, the expert in Cultural Heritage, makes quite a hit at headquarters!
