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.

The protest at school continues, and there is tension among the teachers and the principal. At home, Renzo has a first encounter with the housekeeper. He finds her a bit odd.

Little Livia is in the backseat as her mom drives another teacher home. She listens, she opens her mouth when she shouldn't, she observes. She draws her conclusions and then bets on them with her mom.

Bettina has tea with Camilla and invites her to a gallery event. Camilla then gets a phone call that requires her attention and she rushes off.

Camilla really is a good friend to Vanda. Vanda, on the other hand, is a bit naive. They have a heart-to-heart talk.

Vanda has a hard time accepting what seems obvious to Camilla. Meanwhile she gets a reality check in the form of a phone call. She's lucky to have Camilla as a friend.

After conceding their little bet, Camilla involves her daughter in a "phony" phone call. There's an incident at Bettina's gallery, where Camilla has gone to pick up a book.

Bettina gives Camilla something fresh to put on and gets the book Camilla came for. Small talk between Gaetano and Camilla leads to some interesting hypotheses about the case he is working on.

The family budget has suffered because of the loan to Vanda. At school, we learn that Camilla knows little about the internet, while Vanda gets an unpleasant phone call during her class.

There is some trouble at home involving little Livietta and Gavina, the new cleaning lady. It has to do with the mother-in-law.

Camilla and Vanda go looking for Mazzeo at his aunt's house. Camilla has a hard time watching her friend play into the hands of the man she is in love with.

Gaetano is pretty sure Camilla knows more than she lets on, and gently gives her a warning. But she can't help herself, and travels once again to Mazzeo's aunt's house.

Kids have livelier imaginations than adults sometimes, and in fact, Livietta can see something in Mazzeo's aunt's drawing that Camilla totally misses.

Bettina and Gaetano are supposed to go to the movies together, but Camilla shows up and Gaetano chooses work over fun. At school, everyone is rejoicing at the news that Mazzeo is on leave of absence.

Gaetano's investigation takes him to the school where Camilla and Vanda teach. Camilla, taking her cue from something Gaetano brings up, can't help doing a bit of investigating on her own.
