Balam (George Chakiris) is the son of the ruler of a Mayan tribe who use wooden swords (with obsidian edges). His father is killed in battle against metal-blade armed rivals led by Hunac Ceel (Leo Gordon). Balam succeeds to the throne, but is convinced by his advisers, including the head priest, to lead his followers away from the Yucatán Peninsula, sail to the American Gulf Coast region, so they might regain their strength and fight again another day.
