The sons of a music-loving insurance broker take extreme measures to find happiness for themselves and others, with some help from the power of music.

An insurance broker who is very fond of music has two sons. The older is in love with a Sicilian girl whose father is against their love; the younger is a disgrace to his father because, of all things, he got a very low mark in music at school.—Salvatore Santangelo <[email protected]>
