When Axel's uncle, Professor Liedenbrock, finds a coded journal describing a path into the center of the Earth, Axel hopes he'll never be able to decipher it--because once the professor sets his mind to something, he'll insist on carrying it out no matter the danger or difficulty. But when Axel himself ends up cracking the journal's code, curiosity gets the better of him, and before he knows it, he and his uncle head to Iceland to find this secret route to unexplored territory.

After being joined by a local guide, Hans, the group descends into a volcano, where Axel is convinced they'll find nothing noteworthy and face nearly certain death. Instead, what awaits is more incredible than any of the travelers could have anticipated.
