Challenger 교수는 아마존 밀림 한가운데에서 잃어버린 공룡의 세계를 찾을 수 있다고 믿는다. 하지만 많은 위험이 도사리고 있다.
'You said that you wanted danger, didn;t you?' says McArdle, the editor of the Daily Gazette. And he sends his young reporter, Malone, on a strange journey into South America with the famous Professor Challenger.
Challenger believes that he can find a lost world full of dinosaurs in the middle of the Amazon Forest. But this world is dangerous to reach, and, once the Professor and his small group of explorers arrive, things get even more dangerous for them.
Will they return alive?
