Journey to the Center of the Earth

Professor Von Hardwigg found the old Icelandic parchment in a bookstore, and his nephew Harry soon deciphered its secret Runic message: there was a path to the center of the earth, and an Icelandic explorer had found it 300 years earlier. The professor, Harry, and their guide Hans are soon plunged into an adventure that includes an underground ocean, prehistoric monsters, and a giant cave man.
