The mystery of Cetinka is finally getting solved, so tune in for this exciting moment. You'll even find out what it was that smelled like dead bats!

Martina has left her room and is staying in a tent on the beach near the shack where Alessio sleeps. Alessio has a surprise encounter on the beach with the nice lady he'd met once before.

Maria's crush on her Biology teacher is getting way out of hand, although she says she's got it under control. Meanwhile, back at the house, Giacinto is in the bathroom once again, trying to fix the leak. Cetinka joins him to see how he's doing, and from their conversation, we make some interesting new discoveries.

After a long day's work, Alessio is invited to eat dinner with his hosts, but he soon realizes that there's a lot of tension in the air.

At work, Lele is preoccupied with the Cetinka problem, but then his superior gives him new things to worry about. And if that weren't enough, Grandpa Libero calls him about more missing money and more suspicions, pointing to Giacinto of course.

At the beach club Alessio does a little of everything: he waits tables, leads an exercise session on the beach, and takes care of the deliveries. He also meets someone!

At the end of his day's work, Alessio wrecks the truck he'd loaded, and has to stay on at the beach club for ten more days of work to pay for the damages.

Alessio is stuck at the beach because his scooter has a flat tire. In order to get it fixed he looks for work at the beach club where he had fallen asleep the night before.

Some money disappears from Libero's pocket and he immediately suspects Cetinka's boyfriend. Lele doesn't think he should be accusing anyone without proof, and Libero makes a crack about old people. In order to understand the double-entendre, you need to know that a stufa is a heater and that stufare is to be a bore.

Wanting to rest, Alessio finds an old kayak on the beach and falls asleep in it. What could possibly happen?

The shower is finally getting fixed by a plumber who's dreaming of having his own business, which makes Libero kind of nervous. And Aunt Alice is having a hard time with her boyfriend.

Alessio flunks out and his parents aren't letting him go on the trip he's been planning for a year. He decides to take things into his own hands.

Cetinka's Polish specialty, an onion and mustard soup, doesn't go down well with the Martini family.

It's the last day of school and Alessio, together with two buddies, set off the alarm for a bomb at school in order to throw water balloons at everyone. The three friends are planning a trip around Europe by train. First rule: There are no rules.

Lele's mother-in-law can't bear the idea of having a foreigner in the house taking care of the kids. As usual, she unwittingly betrays her ignorance as well as her bigotry. But privately, Lele isn't totally convinced either.
