A group of NASA hyper-sleep researchers are conducting tests in an abandoned underground facility in the Nevada desert. One subject has died during the test, and NASA has sent Captain Hickock to investigate. What he finds is more horrific than the death itself. The scientists, guided by Dr. Erhart (Academy Award winner Louise Fletcher, ONE FLEW OVER THE CUCKOO'S NEST) and Dr. Van Fleet (James Hong, BIG TROUBLE IN LITTLE CHINA) have broken the boundaries of dream-state sleep and have tapped into a parallel dimension, ushering in an evil alien being that can assume any life form it chooses. Can our heroes survive the horror of the SHADOWZONE?
