In 1964, a group of British seven-year-olds were interviewed about their lives and dreams in a groundbreaking television documentary, "Seven Up." Since then, in one of the greatest projects in television history, renowned director Michael Apted has returned to film the same subjects every seven years, tracking their ups and downs. POV, which presented the U.S. broadcast premiere of "49 Up" in 2007, returns with "56 Up" to find the group settling into middle age and surprisingly upbeat. Through marriage and childbirth, poverty and illness, the "kids" have come to terms with both hope and disappointment.
