Deep beneath the ice-encased surface of Antarctica, a vast underground labyrinth has been discovered. In one of its caves, the remains of an ancient settlement have been found, dating back approximately five million years — before the appearance of the earliest human ancestors. 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 determine the origin of a statuette carved from a single diamond found in the underground settlement. But the dark tunnels, caves, and underground rivers conceal more than just this secret. The scientists begin to understand quite quickly that they are not alone in this mysterious labyrinth.
