Adriano decides to leave running the factory to Marcello and goes off on his own to work on his other projects. But country roads are dangerous in the pouring rain...

Adriano is very happy with how things have been going for the new Olivetti portable typewriter, but his siblings and partners in the business are not so happy. For one thing, they don't like not seeing any of the profits.

Teresa and Libero go to the movies together, and things seem great. But Libero has something important to tell her, something she had no idea about.

The "Lettera 22" portable typewriter is selling well, although Mauro isn't in complete agreement about the price. Libero and Teresa make some plans, and Mister Dalmasso comes around again.

Adriano shows Karen Bates around the new building and she writes her report. The new portable typewriter designed by Libero is finally ready.

Teresa goes back to the factory, and finds out she has talent. Karen Bates, the American photographer, comes to visit Adriano, and he sees right away how he can involve her in one of his projects.

We don't want to give away the ending, so let's just say that Giacomo goes back to the cafe where the redhead works and... who shows up, but Mario.

Paola is more clearheaded after a night's sleep. Adriano isn't happy, but he has other things to think about such as the new plans for the compact typewriter. He and Libero get a visit from the girl-thief again.

After discovering that Mario isn't really ill, Giacomo goes looking for Professor Stern once again, hoping to find some answers.

Paola is having trouble with Carlo and shows up at Adriano's in search of consolation.

Just when Mario felt he was getting his family back, a little karma comes his way to stir things up.

Everyone is talking about Adriano Olivetti, both on Italian soil and abroad. His innovative ideas are creating quite a stir and people worry that he might be a communist.

Giacomo finds a way to obtain the money he needs for Mario. There are strings attached, however, and he informs his sister about it. Giacomo makes a surprise visit to Mario's house, and Ginevra makes a surprise phone call to Mario. Things are closing in on him from all sides.

Adriano knows what kind of portable typewriter he wants to build and he knows who can build it. He thinks he knows what people want, even better than the people themselves.

Maybe, just maybe, Mario is starting to feel bad about what he is doing. Giacomo confides in his sister about the money he needs, and Mario has a surprise encounter at a vending machine he is supplying.
