When the most important friend in her life seems to have disappeared without a trace, Elena Greco, a now-elderly woman immersed in a house full of books, turns on her computer and starts writing the story of their friendship.

Ever since he was a child, the seventeen-years-old Edoardo has suffered from a malformation of the foreskin that stops him from masturbating and makes him insecure and ill at ease with girls. Shut up in his sexless microcosm, Edoardo reacts with irritation to the pressures of the outside world, which do nothing but exacerbate his insecurity. Forced against his will to emerge from the shadows in which he has hidden for years, Edoardo will initially try to solve his problem by clumsy stratagems before finding, at last, the courage to face his own fears.
