plot -
Dr. Abner Perry, a British Victorian scientist, and his US financier David Innes make a test run of their Iron Mole drilling machine in a Welsh mountain. While drilling underground, the extreme heat emanating from the magma around the Mole knocks the duo out and makes them temporarily lose control over where the machine is taking them. After it passes through the magma crust and gets closer to the Earth's core, the temperature inside the Mole starts to lower, and the duo regains consciousness. Perry and Innes eventually reach a surface where they can safely get out. The two notice they are in a strange land filled with the flora and fauna of prehistoric times. They are eventually captured by the Sagoths, ape-like creatures, who aim to enslave every human tribe there. The Sagoths are themselves ruled by a species of telepathic flying reptiles, the Mahars (Pterodactyls with parrot-like beaks).
 
The Mahars have the power of mind control. David falls for the enslaved Princess Dia. She is eventually chosen as a sacrificial victim in the Mahar city, while David is put to work in the magma mines and Perry visits the library. Worried about Dia, David incites a riot within the mine and is captured with Ra, another rebellious slave. The two are sent to the arena where a crowd of slaves watch. The Mahars send a giant dinosaur to kill the duo...
