Professor Challenger and a crew of explorers embark on an expedition in search of a mythical plateau in South America. The party is not there long before the jungle reveals its secrets: a primitive ape-man, a Pterodactyl, a massive Brontosaurus, and more monstrous beasts of the Jurassic age.—yusufpiskin

Professor Challenger comes back from South America with tales of a plateau where millions-of-years-extinct dinosaurs roam. When he is treated with derision he challenges all present to accompany him to witness this world. He gets a few volunteers and they set off to see for themselves the Lost World.—grantss
