Scott Wolter, a forensic geologist known for reading stone as physical evidence, travels from Hawaii to the American Southwest chasing artifacts that do not fit the standard timeline of the continent's history. In Hawaii he examines evidence some read as proof that Polynesian voyagers reached the California coast long before Columbus, weighing currents, artifacts, and oral tradition against the archaeological consensus. In the Southwest he turns to the Grand Canyon, where restricted zones and a controversial 1909 newspaper account have fueled a century of claims about a hidden Egyptian city carved into the rock. Wolter treats each site as a crime scene, applying geological dating and material analysis rather than speculation, and interviews researchers and locals who have chased these stories for decades. The film does not resolve every mystery it raises, but it shows the physical work behind the claims: rock samples, cave entrances, and the gap between what officials say was found and what was quietly sealed off. It runs as a two-part investigation stitched into one feature.
