Dragan Petrović, a single father, formed a band with his three sons who are minors, so he could keep the family together. They do not know the notes, they play by ear and because of that, their music does not sound perfect. There are no music teachers in their village. The closest school is too far away for a single father who lives on the margins of society. Thanks to the boy's talent and his persistence, Dragan manages to enroll his oldest son at the prestigious music school. While the story is about Dragan fighting with all of his might to provide a better future for his children, deep down, the single father is facing his past permeated with hardships and loss.
