Jean Kennedy Smith is the last surviving member of her generation. She was the eighth of nine children of Joseph and Rose Kennedy. Her brother John Fitzgerald Kennedy was the youngest-ever president of the United States of America. A beacon of hope, not only for the USA, but also for the Irish immigrant family striving for higher things. In an exclusive interview in her New York apartment, his younger sister talks about her childhood in a large Irish-American family, the constant sporting rivalry between the siblings, and very privately about her brother, the most powerful man in the world. With the aid of private footage, the documentary tells of the everyday lives of the Kennedys.
