From her birth, Constance has been bound by an unbreakable love with her grandmother, Rose, an elegant Parisian with a mysterious and fascinating past. One event seems to have particularly marked her life: the three months of filming in Palermo of Lucino Visconti's cult movie, The Leopard, in which she participated as a costume designer in her youth. However, Rose keeps her memories like a secret, shared only through the scent of orange blossoms, a fragrance sent to her every year since 1963 by an unknown sender. To honor the promise she made to her beloved grandmother Rose, Constance must follow the traces. She will need to conquer wild Palermo, capture its voices, its sounds, its smells, its tastes, and all that the hearts hide. In the labyrinth of the streets of this great Sicilian port, in front of the splendor of its palaces and within the charms of its history, Constance will try to find her own path.
