Camilla isn't capable of saying no, even when she says no. But she's taking a huge risk for her student, Sammy.

Camilla has gotten quite a scare, but fortunately, she's fine. She has two conversations, one with the police inspector and one with her husband.

A harmless waste paper basket fire in the classroom gives our Professor an idea. She engages the help of one of her students.

This evening Camilla's mother will take care of Livia, who is complaining about the dog again. Camilla and her husband go to the opening of an art gallery, where they have a hard time finding the appropriate words when meeting the artist.

Commissioner Berardi shows up at the gallery opening, and Camilla exchanges a few words with him. This doesn't go unnoticed by the gallery owner, who is very curious. Meanwhile, Camilla's husband has a bizarre conversation with the artist.

Camilla gets her husband to help with the case by invoking her dead father and concocting a story about playing Lotto.

Camilla is taking risks to figure out who killed Nicola. But Commissioner Berardi shows up in time to whisk her away. He's none too happy about her interfering, but in the end, she gives him a hand by identifying some suspects.

Camilla goes to the police station to identify the two thugs who had attacked her, and who sold the drugs to Marta. She also confronts Marta who has been brought in for questioning, and who is wondering who on earth Camilla is, and what she wants from her.

Camilla's husband and daughter watch the video recording of the missed game on TV while Camilla decides what to do the next day (with the help of her dog), and enlists her husband's help.

Camilla visits Marta to try and talk some sense into her, but then they both look out the window and see trouble coming in the form of two thugs Marta recognizes. Of course, Renzo is blithely reading the paper in the car, and has Camilla's cell phone. What to do?

Camilla finally proves to Marta, at great risk, that she just wants to help. And Marta tells her the truth.

Marta tells Camilla what actually happened the night Nicola was killed. Lots of things start to make sense.

Marta goes to the police with Camilla and realizes it was the right thing to do. As agreed upon, Berardi takes Camilla to dinner, where he tells her how the case was resolved. They get a surprise visit, too.

Marta seems to have come back to life, and is no longer alone. Camilla is back with her famiily, and everything has turned out for the best, even for their four-footed friends.

There's a problem at school, and of course, our Prof (short for professore [professor, teacher], the affectionate, abbreviated term students use in addressing a teacher) has to investigate.
