Day two for Guido at the Health Center. It doesn't start well. Meanwhile, Grandpa Libero has his hands full at home with Lele Ju and a visit from Fausto.

A new season (with a new look) and a new episode find Camilla and her family getting ready to start the day. The TV is on and Camilla spies her friend Gaetano on the news, getting involved in a new case. Renzo comes back from buying the newspaper, and gets some unpleasant news from the nosy portinaia (female doorkeeper).

Lorenzo's mother meets Maya's fake family and the marriage takes place. Afterwards, however, during the reception, there's a "disturbance."

Dafne and her father are starting to settle in at home. He did some grocery shopping and is fixing dinner. She told him about her day at work.

Alberto Angela tells us how these caves and their internal structures were created. The key is something very simple. Water.

Guido goes to see an old widow, who isn't a willing patient. Maria shows up at the Health Center as planned.

Gaetano is at the crime scene and two young witnesses work with a sketch artist to recreate the suspect's face. Just as we suspected, there was indeed a problem with taking Camilla's VW to drive Renzo and Livietta to their appointments. We discover who the new principal of the school is. Camilla's class is having fun as they wait for her to show up (late).

Maya's family provides some lively music, but there is plenty of tension, and Lorenzo's mother jumps to conclusions when her necklace goes missing. Maya is heartbroken and almost ready to give up and go home.

Dafne takes her lunch break with her new co-worker Camilla and learns a little more about her. At the hairdresser, Dafne gets a phone call from Viola.

We spend some more time in the spectacular Frasassi Caves, and this time we see the famous "Room of the Candles" filled with stalagmites that look like candles ready to be lit. Alberto Angela also discusses the colors in this place, as well as the "sounds of silence."

Grandpa Libero goes over to the university with Fausto, looking for Alberto. Maria doesn't show up at school to pick up Annuccia, and so Annuccia starts walking home by herself. Nowadays kids would never be allowed to leave school unattended.

The witnesses questioned by Torre furnished some important information about the murder. Gaetano meets the new public prosecutor who is not what he expected. Renzo makes the acquaintance of Livietta's substitute ballet instructor.

Lorenzo wants to leave, but Nora and Ugo talk to him about love. Gisela is waiting for the police, who aren't showing up. Meanwhile, Maya has a surprise for everyone.

Dafne is at a party with her friend Viola, and a guy asks her to dance.

The Great Cave of the Wind in Frasassi is a natural wonder, but it also bears witness to the passing of time. Speologists are still exploring it and discovering new wonders.
