Gregorio, a 30-something guy with a perfect life and Azzurra, same age, but with a shitty life, are two strangers. They do not know each other and they have nothing in common... except for their father, Marcello.
When Marcello suddenly goes missing, Gregorio goes through his stuff and finds a magic hourglass to travel back in time to his memories by looking at a picture. He discovers that he has a secret half-sister and that Marcello is somewhere in the ‘90s. To find him he needs Azzurra’s help, and her memories.
She initially refuses, but when they realise that they can actually fix the past, it changes everything. To her, this is the chance to save her mother; to him, the chance to get his life back. They know that the path they begin is anything but easy and eventually they will realise that happiness for both of them is impossible.
What they do not know is that they might not get what they want, but that along the way they will discover who they really are.
