When Professor Von Hardwigg and his nephew Henry discover a mysterious parchment, little do they know that it will change their lives forever.
After many hours of studying the manuscript, and a great deal of painstaking research, they finally decipher the hidden code. It dates back to the sixteenth century, and is written by an Icelandic philosopher who claims to have found a passage to the centre of the Earth. Is it a hoax? Or is it the greatest scientific discovery of the day?
There is only one way for them to find out. And so begins an adventure where the two men, accompanied by their guide Hans Bjelke, set out to climb Mount Sneffels. On reaching the top of the mountain, they search for the crater that will supposedly take them to the centre of the Earth.
The promise of finding a subterranean fantasy world, filled with prehistoric life forms and mythical monsters, drives them on. Will they really reach the centre of the Earth, or is it all a myth?
