Plot

In an alien landscape, Jerzy Colsowicz experiences a vision of a powerful and destructive storm brought about by a young human girl. His colleague, an enigmatic Christ-like figure, tells his bald pupils about the centuries-long cosmic conflict between Zatteen, an evil inter-spatial force of immense magnitude with powerful psychic abilities, and his benevolent arch-rival Yahweh. Zatteen escaped to the planet Earth centuries ago, and though he was eventually tracked down and killed by Yahweh, his spirit lives on in the minds of humankind, waiting for an opportunity to reemerge and wreak havoc. The figure tells his disciples that Zatteen had produced dozens of children with human women before his death, and these descendants continue to populate the Earth.
