In 1931, an expedition team arrives at a campsite in Antarctica...to find its crew of men and sled dogs strewn and dead. Some are hideously mangled, as if in rage--some have been dissected in a curious and cold-blooded manner. One man is missing. But a still more horrific sight is the star-shaped mound of snow nearby...for under its five points is another mass grave--and what lies there is not remotely human!
