Twenty years after a devastating war reshaped the world, an elderly man and his spirited grandson Conan are the only survivors of their former village. Convinced they are the last humans left, they one day find a woman unconscious on the beach of their isolated island.
When she awakens, the woman named Lana says she was escaping agents from a mechanized fortress island known as Industria. Because Lana is the telepathic granddaughter of famed scientist Dr. Briac Lao, Industria"s officials want her help, believing her powers will aid them in locating the doctor and harnessing his knowledge to reach a potent energy source.
Despite Conan"s and his grandfather"s best attempts, they cannot stop Lana from being taken again when Industrian troops arrive. Determined to free her, Conan sets off on a perilous quest, but the stakes are far greater than he had imagined. The path ahead is riddled with ruins, hidden traps, and the looming threat of Industria"s pursuit.
