In this movie, archaeologists Dr. Roger Bentley and Dr. Jud Bellamin stumble upon a race of albinos living deep under the Earth. They keep mutant mole men as their slaves to harvest mushrooms, their main food source, since they can grow and thrive without sunlight. The Sumerian albinos' ancestors moved into the subterranean after the cataclysmic floods in ancient Mesopotamia. Whenever their population increases, they sacrifice old people to the Eye of Ishtar, which is really natural light coming from the surface. These people have lived underground for so long that they are weakened by bright light which the archaeologists brought in the form of a flashlight. However, there is one girl named Adad who has natural Caucasian skin who is disdained by the others since she has the "mark of darkness." They believe the men are messengers of Ishtar, their goddess. When one of the archaeologists is killed by a mole person, Elinu, the High Priest, realizes they are not gods. He orders their capture and takes the torch to control the Mole People, not knowing the battery is flat. The archaeologists are then sent to the Eye just as the Mole People rebel. Adad goes to the Eye only to realize its true nature and the men had survived. They then leave for the surface. Unfortunately, Adad dies after reaching the surface when an earthquake causes a column to fall over and crush her. Its likely the mole people swaped roles and used the albinos as slaves instead.
