Salvatore Cannavone (Domenico Modugno) is a Sicilian cobbler-cum-shoe salesman who has worked for thirty years in New York City. He returns to his hometown where, although of modest means in America, he is considered a wealthy man and becomes the centre of attraction. He begins to live with his brother Raffaele (Pippo Franco), his wife Rosa (Luciana Paluzzi), and his stepdaughter Mariuccia (Eleonora Giorgi) and, starting from their first meet, he and Mariuccia get busy with games of seduction. Raffaelle notices Salvatore's interest in Mariuccia and attempts to make use of it to have him stay at their house and to exploit his wealth. On the other hand, Salvatore also has an eye on voluptuous Rosa and both Mariuccia and Rosa begin to see Salvatore's passion as a means to secure the economic benefits he provides, which eventually leads to a peculiar ménage à trois. Things get even more complicated when Mariuccia is betrothed to another man.
