What Happens, Part by Part (Contains Spoilers)
The challenge
Malone wants to do something heroic so that Gladys will marry him. His newspaper sends him to interview Professor Challenger, who claims to have found living prehistoric creatures in South America. At a public lecture, Challenger dares anyone to test his claim. Malone, Summerlee and Lord John Roxton volunteer.
The journey
The explorers travel up the Amazon and through jungle to a high plateau surrounded by cliffs. They cross onto it by felling a tree as a bridge. A treacherous porter topples the tree, trapping them on the plateau.
The plateau
They find living dinosaurs, including iguanodons and a terrifying meat-eater, and a swamp full of pterodactyls. Summerlee is forced to admit Challenger was right. Malone explores alone at night and narrowly escapes a predator.
Ape-men
The explorers are captured by a tribe of ape-men who are at war with an Indigenous people living on the plateau. Lord John and Malone free the others, and with the Indigenous people, they defeat the ape-men. Their new allies help them find a way down.
The ending
Back in London, skeptics doubt the story. Challenger releases a live pterodactyl he brought back, which flies away over the city. Malone returns to Gladys, only to learn she has married a clerk. Unbothered, he plans a new expedition with Lord John.
