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.

Sir Arthur Conan Doyle's "The Lost World" is a classic adventure story published in 1912. A scientific expedition embarks on a journey to South America. The troupe seeks to verify reports that prehistoric life still exists in a remote interior region of the continent. Written by Mandemus

Professor Challenger reveals the existence of a remote plateau in the Amazon jungle where dinosaurs have survived. He returns there leading an expedition. Not only are dinosaurs found and confronted, but also highly evolved apes, Amazonian Indians who think Challenger a god, and, on the way, the attractive orphaned niece of a lonely missionary. Theology intervenes in this exercise in vindicating Darwin and the missionary twice attempts to sabotage the mission. After much excitement, love is found in unexpected places, and, confronted by civilization, as represented by the Royal Society in London, Challenger changes his story. Written by Stewart Naunton
