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.

Commissioner Manara and Inspector Rubino figure out who wrote the love letters and Lara conducts the appropriate interrogation.

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.

An important new element in the investigation comes into play: some romantic letters found at the victim's house. Lara is comparing the handwriting to that of the note found next to his dead body.

With the information given by Ginevra, Luca and Lara go to the pharmacy to find out about recent sales of two drugs. When combined, the drugs are fatally poisonous. That same day the funeral takes place and the whole town is there. Manara takes advantage of this to look for new suspects.

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!

Lara decides to question the medical examiner Ginevra, the last person to have seen the victim alive. Manara had a different idea about how to handle his witness.

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.

Sardi wants to comfort Toscani after he'd been punched in the face by the bass drum player. Manara wonders where people go in the evening, and Lara, after seeing the Commissioner in a car talking to Ginevra, goes home and confides in her Aunt about why she can't stand him.

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