The Cormorant is a former summer camp at the mouth of the river nearby Pisa. This is where young Mario lives. Everybody nicknames him B.B. (for Bugs Bunny) because of his teeth. Around him gravitate a range of colorful characters, all more weird than the other, but with whom he gets along. As far he is concerned, B.B. works hard with a view to earning enough money for being able some day to buy a plane ticket to the USA, where he dreams of joining an uncle who lives in New York and becoming a singer there. But one day, his American uncle returns.
