Archaeologist Mason time travels to a tribe, using modern knowledge to build civilization. He chooses the barren Iron Eagle Ridge, taking in Chloe, Rhea, and Willow, believing it holds mineral deposits. Mason faces the Jackal Tribe, ambushing and repelling them with fire pots and traps. He leads them to find water, smelt iron, and plant millet, building a city. The women become partners. Mason transforms from scholar to pioneer, vowing to spread civilization from Iron Eagle Ridge.
