The Cave

Under the ice-encased surface of Antarctica, a huge underground labyrinth has been discovered.

In one of its caves, the remains of an ancient settlement have been found, dating back about five million years, that is, even before the appearance of the very first ancestors of humans. Who lived here in those distant times? 

A team of anthropologist scientists must descend to the center of the Earth to unravel this mystery and also find out the origin of the figurine found in the underground settlement, carved from solid diamond. 
But the dark tunnels, caves, and underground rivers hide not only this secret.

The scientists quickly begin to realize that they are not alone in this mysterious labyrinth.
