Explorer Professor Challenger is taking quite a beating in the London press thanks to his claim that living dinosaurs exist in the far reaches of the Amazon. Newspaper reporter Edward Malone learns that this claim originates from a diary given to him by fellow explorer Maple White''s daughter Paula. Malone''s paper funds an expedition to rescue Maple White who has been marooned at the top of a high plateau. Joined by renowned hunter John Roxton and others the group goes to South America where they do indeed find a plateau inhabited by pre-historic creatures one of which they even manage to bring back to London with them.
