Ida is a married woman in her late thirties, who lives in Milan and works at a radio station. Her mother wants to renovate the family apartment in Messina, to put it up for sale and asks her daughter to sort through her things - to decide what to keep and what to throw away. Surrounded by the objects of her past, Ida is forced to deal with the trauma she experienced as a girl, twenty-three years earlier, when her father left one morning, never to return.
