The Immature - The Series

Lorenzo Romanini is a real estate agent and a classic "big baby" who still lives with his parents and refuses to move out on his own, much to his father Maurizio's despair. Piero Mistico is a single radio host who, to avoid a relationship, tells his girlfriends Cinzia and Sandra that he's married and has a child. Virgilio has a struggling DVD rental business and had a falling out with his best friend Piero in high school. Francesca Coppetti, a successful chef, undergoes sessions to "cure" her sex addiction and is saved by her tutor Gianni while she's kissing her colleague Amodeo in the car after dinner. Luisa Cappiello is a very confused single mother who is on the verge of becoming an architect. Serena Serafini is a rich and spoiled woman whose husband has been targeted by the Guardia di Finanza, while her daughter Lucrezia is having an affair with Savino, the son of an ATAC bus driver and therefore not of their social class.

Serena is completely broke and living in a boarding house, but she's not supposed to know. When her daughter is caught stealing money from a classmate, she starts making deliveries to Mimmo "the Frenchman." Piero struggles to manage the two lovers and finally manages to come clean to Virgilio about the fact that he hadn't actually slept with his girlfriend Anita twenty years earlier. Lorenzo and Luisa, using the excuse of studying, begin spending a lot of time together, but neither can bring themselves to make the first move. Meanwhile, Francesca is obsessed with her new math teacher, Daniele Di Giulio. The group decides to pressure Professor Russo, but then, in a fake robbery attempt, Piero gets the worst of it when she punches him and ends up in the hospital. There, they also find Di Giulio, who was brought there by Francesca after being attacked by thugs outside his restaurant.

The students are specially quizzed by Professor Russo, and they all get top marks in philosophy. Serena enjoys working with Mimmo. Piero is having trouble because Sandra is harassing him, while Cinzia demands a photo of her supposed son, so she shows him a photo of Virgilio's daughter as a child. Lorenzo and Luisa arrange to meet on the tram to find their soul mate. Virgilio returns home to get some things and leaves without explaining himself to his wife; meanwhile, he begins to feel good about Doriana. Professor Russo begins to take care of Simona Fabbri, a difficult student, but must also face her own problems. Professor Di Giulio returns to class and helps Francesca with her assignment; outside of school, however, the student harshly scolds him. The day of the teachers' parent-teacher meeting arrives.
