This series begins with Diabolik, the greatest criminal of Italian comics or fumetti as they are called because of the "clouds of smoke" (speech bubbles) present in comic strips. Fumo means "smoke." In this segment, various personalities describe the character Diabolik, both the good and the bad.

Every serious vintage car collector must have a Ferrari Daytona. Some of the characteristics of this car are described in this segment.

Surrounded by her friends, Ilaria makes a video call to her parents. She downplays the situation but her father is pretty upset.

Imma manages to interview Stacchio's father, who is not exactly forthcoming. Back home, Imma gets complaints about her cooking and they listen to the news report about the missing boy.

We see the underside of a Ferrari as an inspection is carried out. Carmine Sessa, a classic car expert, talks about the Spider model and the Daytona model, which was built in a limited quantity, almost exclusively for the American market. Fun "fact": Some say the yellow color was named Fly, standing for "Ferrari Light yellow." The color was suggested by Fiamma Breschi (a close friend of Enzo Ferrari's). Fiamma means "flame" but she didn't want the color to be Giallo Fiamma "flame yellow" (named after her) and suggested "fly."

Ilaria has to call her parents to tell them she is pregnant. She has a story ready for them, but her friends find it far-fetched.

Leaving school, Valentina and her friend meet up with a certain Samuel who has a little present for Valentina. Imma and Calogiuri see Stacchio's friends and ask them some questions, with the pretext that Calogiuri had lost his dog.

The passion for vintage cars can become a real disease. Being the owner of a car and being a collector are two different things.

While they are placing the mirror in Berna's apartment, they see an interview on TV with someone they had known back in the day. Back home, they encourage Francesca to make a certain phone call, showing her how it could play out.

Imma gets some information from her "helpful" colleague and goes to Eustacchio's school to find out more. Viewers might recognize his teacher.

There are a great many unique automobiles in the collection. In the early twentieth century, there was no metallic paint, so other solutions were found to produce a special finish, such as Lunar Chrome, a technique using mother of pearl and fish scales.

While delivering the mirror to their friend, Vincenzo wonders why the Leaning Tower of Pisa leans. They have a ways to go on foot and a while to wait at the door, so there is plenty of time for Andrea to explain.

Calogiuri shows up at Imma's office with a possible piece of evidence, meriting a trip to see Stacchio again. They head out together but there is some troubling news awaiting them there.

Italy has an important tradition of auto d'epoca (vintage cars) and auto da corsa (race cars) and RAI TV has dedicated a documentary series to this topic. This first segment is introduced by former racing driver René Arnoux, who competed in 12 Formula One seasons. You might notice his French accent. It also features Silvia Nicolis, daughter of the collector of vintage cars, Luciano Nicolis.

Francesca is anxious about Vincenzo's phone call from Iceland. He comes back from the phone call happy, but not everyone is as happy as he is.
