In a sunny district of Naples where everyone knows each other, Mario (Vincenzo Antonucci) and Lino (Francesco Pellegrino), two inseparable friends, live days that are always the same. Until Lino's little sister, Annaluce (Sophia Guastaferro), makes a miracle and becomes the patron saint of the district. For both, since that moment, a door opens to a new world that will lead them to take different paths, risking everything, even the most important thing they have: their fraternal friendship.
