Arianna was born three times : first as a boy, three years later as a girl and a third time at the age of 19 during a summer in an old family house in the countryside. In spite of her age, she has still not got her periods and the prescribed hormones don't seem to be too effective. The presence of a younger cousin revives her musings, while memories resurface, along with something more mysterious. Slowly but surely, the pieces of a new intersexual identity fall into place.
