In 1929, for the first time in history a Graf Zeppelin circumnavigated the globe. Beneath the enormous airship hung a gondola to accommodate the lucky passengers and crew for the duration of the 21-day voyage, among them the young journalist Lady Grace Drummond-Hay, reporting for the Hearst media empire. Based upon her letters and diaries and told exclusively through archival and newsreel film from the time, this film relives the incredible voyage.
