Canadian actress and filmmaker Sarah Polley investigates certain secrets related to her mother, interviewing a group of family members and friends whose reliability varies depending on their implication in the events, which are remembered in different ways; so a trail of questions remains to be answered, because memory is always changing and the discovery of truth often depends on who is telling the tale.
