In China's Bayan Har mountains, the legend goes, cave explorers found 716 stone disks etched with tiny spiral grooves and markings some readers claim form a hieroglyphic-like script. The film lays out the Dropa Stones story from that alleged discovery forward: tales of a crashed craft, a dwarfish people called the Dropa or Dzopa who supposedly lived among local villagers, and translations claiming the grooves describe an extraterrestrial landing. Researchers, historians, and UFO investigators walk through the physical description of the disks, the competing accounts of who examined them and when, and the total absence of any disk that has surfaced for independent testing today. The documentary treats the case the way it has to be treated, as an unverifiable legend with no surviving artifact, no named museum holding, and origins that trace mostly to a single writer's account decades after the supposed find. It sets the Dropa claims alongside China's actual archaeological record and folklore about the region, and leaves the authenticity question open rather than resolved, since nothing remains to test.
