Amelia Earhart vanished over the Pacific in 1937 during her attempt to fly around the world, but this film follows a quieter story left behind on land: her younger sister Muriel, known in the family as "Pidge." Through home movies, letters, and interviews with relatives and historians, the documentary traces how Muriel spent decades fielding theories, hoaxes, and reporters, working to keep her sister's memory intact rather than letting it dissolve into myth. It moves between the familiar outline of Amelia's aviation career, her record flights and her disappearance near Howland Island, and the private toll on the family she left behind. Archival photographs and flight records anchor the historical sections, while present-day interviews with Earhart researchers weigh the competing disappearance theories without settling on one. The film's real interest is in legacy-keeping itself: what it takes for a family member to manage fame, speculation, and grief for eighty years, and how that work shapes the public story as much as the vanishing did.
