The first stop is Italy's easternmost point, the Punta Palascìa and its 19th century lighthouse. Alberto Angela then shows us another site in the Apulia region, Castel del Monte, a breathtaking crown-shaped castle built by Frederick II in the early 1200s.

Marta has conversations with both Manara and Raimondi, neither of which is she too happy about. The term innominato or unnamed makes reference to the evil character in Alessandro Manzoni's novel, I Promessi Sposi (The Betrothed).

Ferruccio, the kitchen hand, tells Dante about a conversation he overheard and this creates a little friction between Eva and Dante. Lorenzo hasn't been showing up for meals at the restaurant and Eva learns why.

Peppino buys some groceries for Martino and Marti' is none too happy with the bill. He goes over what Peppino bought, giving the quantity as due and du' [short for due (two)] for the canned tomatoes, beer etc. Often, this due isn't a literal two, but means a small amount. You frequently hear the du' at fruit and vegetable shops or markets, where customers might ask for just a little bit of something, such as "du' ciliegie" [cherries]. The du' is also a polite way of preventing the vendor from heaping produce on the scale.

We learn why Dalmasso asked Mauro to stay on at the Olivetti firm. Adriano pays a visit to Mauro's house to find out if his suspicions are correct.

In this last segment, Daniela focuses on when the past participle of a verb in the present perfect has to agree (in number and gender) with the direct object pronoun when using compound pronouns. It's a bit tricky.

Arianna and Simone show us the historic center of this city on Sicily's west coast. Points of interest include its Casbah, where ceramic tile artworks tell of the city's Arab history, an unusual central-plan church; and the Satyr Museum.

Manara sneaks up on the winery owner's daughter and the stockroom guy. Toscani and Sardi ask Manara to run an errand, claiming they have 41° C fevers [105.8° F] as a ruse to get him to come over.

Peppino brings Sally, the Latin American woman from the gas station, to the hideout, thinking he is doing Martino a big favor.

After his encounter with Mauro, Adriano faints on the sidewalk. Grazia reads about his fainting in the newspaper and visits Adriano in the hospital.

Adriano has invited us to the baptism of his son Philip. It allows us to get a glimpse of one of the most beautiful places to visit in Palermo, the Palatine Chapel. The priest tells the congregation about the consecration of this famous basilica in 1040.

Wonderful aerial photography shows Castel del Monte and its crown-like octagonal shape. Frederick II was particularly fond of the castle because it was an ideal location to hunt small game with his falcons.

Luca goes to see Sardi and Toscani. He opens the door and sees a familiar face he hasn't seen in a while. They go out for some seafood together.

Eva practices opening the safe, and Dante goes to the market, none too happy about his friction with Eva. He has an unusual encounter there.

The disappearance of Martino hasn't gone unnoticed after all. A TV crew has shown up in town. Naturally, Peppino rushes off in his Ape (three-wheeler) to give Martino the good news.
