The rags to riches story of identical twins Jenny and Rosie is set against the glittering backdrop of high society in America and Europe before the onset of the Second World War. They had a colourful life where nature's duplicity enabled a highly successful career as dancers which made them 'stars'. And yet, lurking behind their glamorous story of fame, fortune, mistaken identity, millionaires, love and sisterly devotion - that made them legends - is another of rivalry, duplicity and tragedy.
