Can a suicide have a guilty party who determined the choice of the one who committed it? Teresa, a sixteen-year-old girl who has been studying in a foreign school for two years, can't accept her mother Laura's suicide, as her father Stefano, a respected and well-liked doctor in his community, seems to do by attributing her mother's gesture to depression. To uncover the truth, Teresa must delve into her memory, but above all find out what happened to her mother, who, after abandoning a brilliant managerial career, spent two years in voluntary isolation. The girl runs away from home with her only friend, Miki, a rebellious and ill-reputed eighteen-year-old who is willing to help her because he is in love with her. The journey, which was supposed to be a romantic escape for Miki, becomes a way for Teresa to retrace the uncertain threads of memory. By revisiting the places and meeting the people from the past, Teresa discovers the shocking truth about her mother's death.
