During the night, as the scientists look on in shock, the husky mutates and attacks the other dogs in the camp. The team soon realises that a bizarre alien life-form has found its way into their midst.

In the coming days - more pieces of the riddle are put together. Centuries ago - an alien spaceship had crash landed in the Antarctic. The pilot was thrown clear and eventually froze in the ice. The creature is eventually uncovered 100 000 years later by a group of Norwegian scientists who thaw the creature out. The alien comes to life and proves to be extremely hostile. It has the ability to alter its own cell structure to that of a consumed organism, and thus imitate the victim almost perfectly.
