Concetta is the eldest daughter of Peppino, a puppeteer leading a traveling variety troupe. She performs alongside her father and younger sisters, Fiorina and Giulietta, mastering the art of puppet manipulation. Originally from Genoa, Italy, economic hardship drives the family to emigrate to Argentina.

In Argentina, Concetta continues performing with the family troupe. Their journey intersects again with Marco Rossi when he arrives in Buenos Aires searching for his mother. Concetta and her family provide Marco vital support, offering temporary shelter and aid during his quest across the country. Throughout the narrative, she maintains a consistent secondary role centered on the troupe's performances and her familial duties.

Her relationships are firmly rooted within her family: she collaborates closely with Peppino during performances, shares puppetry responsibilities with Fiorina, and helps care for their youngest sister, Giulietta. Reuniting with Marco in Buenos Aires underscores her supportive yet static function, as she assists his quest without undergoing personal development. No additional storylines or adaptations explore her background or journey further.
