Intertwining archival footage and previously unseen home videos spanning eight decades with present-day scenes, the film paints an intimate portrait of one of America’s most fascinating families. Cooper and Vanderbilt tell the story of their past and present, losses and loves, and show how, in life, patterns repeat themselves in the most unexpected ways. Drawing on Gloria Vanderbilt’s private archive of letters, home movies, photos and artwork created by her over the years, as well as vintage news footage and newspaper clippings, Nothing Left Unsaid is a journey through a life like no other.
