When Debora's ex-husband, a popular neomelodic singer, loses his life in a stage dive, she worries that her 11-year-old son Ciro may be showing symptoms of depression. Taken to a child psychologist, shy Tommaso, Ciro eventually confesses to him that it's not his father's death that has got him down, it's love for his classmate, the cute Ludovica. The two make a deal: Tommaso will help Ciro to win the affections of Ludovica, while Ciro will give Tommaso a hand at having a chance with his mother.

Tonino Esposito is the son of the fearsome Camorra boss of Rione Sanità, Naples. Unlike him, however, Tonino is clumsy and utterly innocuous—a decent person at heart—and so when his father dies he's passed over in matters of succession. His pride wounded, he doesn't resign himself and tries to be his own boss, only managing to make a fool of himself. When he finds out that his daughter is dating to the son of the judge prosecuting the new boss, Tonino sees the opportunity to prove himself in front of his family and all of Naples.

Ottavio Camaldoli is a professor of Latin and Greek. An honest and gentleman, he is considered a "fool" by everyone around him. But what would happen if this defenseless man, a victim of petty daily abuses in his social life, at work, and even at home, were to receive another man's heart transplant? Especially if this other man, the donor, were a brutal criminal with the sinister nickname of "O Barbiere" (The Barber)? Would Ottavio Camaldoli, after inheriting the heart, automatically become a criminal? Science tells us that these are just silly, ancient beliefs. But what if Donna Carmela, the Barber's ruthless mother, were convinced that her son is still alive thanks to the heart now beating in the professor's chest?
