A story is about young teenage girl, with sister and brothers, a pleasant uncle and aunt, an annoying nanny, a young boy interested in kissing her, a close relationship with the imaginary addressee of her daily diary and her parents' disintegrating marriage - all this in a rented house in a summer resort.
