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

High school professor Guido is a hopeless romantic whose life falls apart after his girlfriend leaves him for another man. Paolo, a former student of his, helps him to exit his depression, only in order to become a PE teacher himself.
