In 1953, Julius and Ethel Rosenberg were executed by the U.S. government, their names seared into history as both martyrs and atomic spies. Today, they remain political icons—hailed by some as heroes and vilified by others as traitors. This film chronicles the efforts of filmmaker Ivy Meeropol to come to terms with the lives and deaths of the Rosenbergs—her grandparents. Meeropol weaves archival footage, family home movies and conversations with her father Michael, his younger brother Robert and other relatives and associates of the Rosenbergs. The result is a deeply personal and sometimes painfully emotional film that paints a never-before-seen portrait of a devoted couple who came to symbolize Cold War hysteria.
