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.

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 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 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.

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.

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.

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.

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.

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

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.

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!

In the presence of Ginevra who has come to thank both Lara and Manara for saving her reputation, they look once again at the painting of Lorenzo. A detail gives them the key to finding the murderer!

Alessio is getting tired of being treated like a slave by Tonino, and tries in vain to rebel. He lets off steam to Martina who understands all too well.

"Quelli che" (those who...), written and performed by the great Enzo Jannacci, lends its ironic and humoristic verses to the soundtrack of Lina Wertmüller's film,"Pasqualino Settebellezze" [Seven Beauties] starring Giancarlo Giannini, and nominated for best foreign film at the 1976 Oscars.

Ciccio gets what he wanted: fancy sneakers. Maria gets what she wanted: a personal appointment with her teacher. But things aren't so simple...
