Two groups of explorers are marooned on a desert planet. Unknown to each other, one group must survive the harsh rigors of primitive life by wit and aide of a powerful alien device. The other, fleeing intertia and despotism, makes an astounding discovery that plunges them into the heart of an inner war. It is the story of the begining of myth and civilization, of the human heart and its struggle for survival between two dimensions, the interior and the exterior, that we by nature straddle, and the unavoidable consequences of choice.
