Leonardo is a young theater enthusiast who has written a comedy for a comedian at sunset, Giordani, and leaves for the Adriatic coast together with the producer Peppino and his assistant to reach the actor and convince him to stage the script. During the journey, which becomes longer and longer and with unusual and bizarre stops, he will soon realize that Peppino's attentions are not disinterested, while he will be attracted by a young and beautiful girl, Paola.

Four thirtysomething university students share a flat in Florence: Leonardo pursues beautiful Letizia, her brother Rocco works night shifts to pay for his rent, Bruno has to graduate to inherit his father-in-law's business (while cheating on his wife with her sister), and Pino dreams of becoming a stand-up comedian.

Tullio Venturini, a retired widower, has a daughter, Anna, who is an actress. However, he is the only one not to know that she works in the porn industry.
