Chubby pre-adolescent Anaïs is spending the summer with her short-tempered mother, her workaholic father, and her beautiful, boy-crazy older sister, Elena. Elena meets and begins dating Fernando, a handsome, older Italian law student, and makes Anaïs a co-conspirator in Fernando's midnight visits to their shared bedroom. Thus is Anaïs--mute witness to her sister's initiation into sex--left raging with jealousy and self-loathing. Anaïs avers that she is ready for her own sexual adventure, but what will happen when she has it?
