It is 1953, a heat wave is sweeping across America and the Grossmans - Ben, Addie and their two children - are moving their lives from the political heart of Washington DC to suburban Long Island. With their future uncertain, life in Long Island starts to cause problems for Ben and Addie. Both begin to wonder if they were meant for more, whether their lives might look different than they planned, and whether their marriage - their family - is worth fighting for. A Long Island Story is a portrait of a couple in crisis, of a unique and fascinating period in US history and of a seemingly perfect family fighting their demons behind closed doors.
