After years of research and exploration, he finds that dinosaurs that were thought to have long been extinct still exist and live somewhere in the heart of Africa. However, his research was ridiculed by his arch-rival Professor Samori (David Warner) and others. To prove his point, he made an appointment with Samory and newspaper intern Edward Malone (Eric McCormack Eric McCormack), and several people went to mysterious Africa to find the lost world. After a long journey, they finally saw the group of ancient creatures. But at this time, the danger came unexpectedly, and the expedition team was trapped in the world of dinosaurs and forced to be involved in the tribal struggle, full of darkness and hardship in front of them.
