Captain Grant sets out on a dangerous voyage to found a Scottish colony on the islands of the Pacific Ocean. But his ship wrecks, and only a half-faded note in a bottle brings fragmentary information about Grant. Lord Glenarvan, at his own risk, goes looking for him, taking with him the captain’s children—Mary and Robert. The route of these brave travelers runs through the mountains and pampas of the American continent, New Zealand, Australia, and the vast Pacific Ocean—where all kinds of adventures await them.
