From a lost expedition to a tepui in Venezuela, Paula White brings the journal of her father explorer Maple White to the eccentric Professor Challenger in London. The journal features sketches of dinosaurs which is enough proof for Challenger to publicly announce that dinosaurs still walk the earth. Met with ridicule at an academic meeting at the Zoological Hall, Challenger reluctantly accepts a newspaper's offer to finance a mission to rescue Maple White. Professor Challenger, Paula White, sportsman Sir John Roxton, news reporter Edward Malone (who is a friend of Roxton and wishes to go on the expedition to impress his fiancée), a skeptical professor Summerlee, an Indian servant Zambo, and Challenger's butler Austin leave for the plateau.
