Il Baracchino, once a temple of laughter, is now a den infested with cockroaches and drunks. But Claudia, a young art director with a stubborn heart, is determined to bring it back to its former glory, gathering an unlikely band of penniless comedians. The only obstacle? Maurizio, the gruff unicorn owner. Will she be able to convince him to give new life to the Baracchino?

Maurizio decides to help Claudia but on his own terms: a super-intensive course in the golden rules of comedy, supported by his laughter machine. While Claudia is not convinced by Maurizio's methods, the machine seems to jam... Meanwhile, Gerry and Larry search for the legendary Perfect Joke, written by Tatiana and hidden in Il Baracchino.
