Heinrich Himmler, head of the SS, believed the Aryan race descended from the lost city of Atlantis, and that its survivors fled to the Himalayas when their homeland sank beneath the sea. This film follows the 1938 German expedition he dispatched to Tibet to hunt for proof, tracing the scientists and SS officers who trekked through the mountains searching for physical evidence of an Aryan-Atlantean bloodline among the Tibetan population. Archival photographs, expedition records, and historian interviews reconstruct how Nazi racial pseudoscience fused with occult theory to produce a genuine state-funded search for a mythical lost civilization. The film treats the expedition as a case study in how the Third Reich's leadership blended real fieldwork, measurements, skull casts, ethnographic surveys, with fantasy, using the language of science to prop up an ideology already decided in advance. It is less about Atlantis than about how far a totalitarian state will go to manufacture the ancestry it wants.
