Professor Lidenbrock discovers a coded message describing a way to travel to the center of the Earth. He and his nephew Axel, along with their guide Hans, enter a volcanic crater in Iceland and have several adventures as they journey underground, facing dangers and seeing prehistoric life. They eventually blast through a rock blockade, which causes a flood that sweeps them down into a volcanic vent. They are ejected from the vent on the island of Stromboli, having traveled over 3,000 miles inside the Earth.
