Forensic geologist Scott Wolter travels to Hawaii to investigate the legend of the Menehune, a mysterious race of small people said to have inhabited the islands long before the arrival of the Polynesians. Through his exploration of ancient stone structures and discussions with local experts, Wolter seeks to determine if these legendary figures were a distinct group of people or a reflection of a complex social hierarchy. His journey takes him across the islands, from the lush landscapes of Kauai to the sacred, restricted grounds of Kaho'olawe, as he pieces together the evidence of a hidden history that challenges conventional understanding of the region's past.
