Arianna is nineteen years old but she still hasn’t had her first period. The hormones that her
gynaecologist has prescribed don’t seem to have any effect on her development, except for a small increase in the size of her breasts that only cause her discomfort. At the beginning of summer, her
parents decide to retake possession of the farmhouse on Lake Bolsena where Arianna grew up till the age of three and where she has never returned. During her stay in the house, old memories start
surfacing, so much so that Arianna decides to stay on when her parents need to go back to the city. The afternoons are slow and silent while Arianna starts inquiring about her body and her past; an encounter with her young cousin celeste - so different and feminine compared to her - and the loss of her virginity with a boy her same age push Arianna to finally confront the true nature of her sexuality and her true identity.
