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).

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).

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.

At the police station, there seems to be a match for the murderer. In class, Camilla does the roll call and discovers Luca Foglietti is absent once again. She goes to the window to investigate.

Camilla gets caught at the school window by the new principal. Having seen what she saw, she tries again to get some information from her students. Meanwhile, Berardi and Torre search the apartment for clues, and Berardi talks to the doorkeeper of the apartment building.

Ferrari finds a plane ticket in the victim's name and calls the travel agency to find out more. Camilla and Martina pick up the kids at dance class and the conversation gets around to the new substitute teacher Camilla had no idea about.

Camilla goes to see Luca's mother and learns why she doesn't want to call the police about her missing son. Gaetano is rushing to the airport, where Torre and Ferrari are waiting for the victim's wife to make an appearance.

Rotunno's wife had heard the news report in the bathroom of the airport, so she made a change of plans in a hurry. At home, Livietta and her mother are having a chat about school, while Camilla's phone keeps ringing and ringing in the living room.

Gaetano gets a different story from the doorman than his wife had given, and even has some new important details to share. Gaetano reports on the case to the prosecutor and brings up dinner again. At home, Camilla mentions the substitute dance teacher to Renzo...

Gaetano and Camilla finally meet. They talk about the case but not only, and they go to Luca's house to talk to his parents.
