After a herd of reindeer are mysteriously found dead following a meteor crash in a remote part of Sweden, soldiers and a geologist are called out to investigate. Just as they discover that the meteor is actually a spaceship, a hideous monster destroys their plane and kills the soldier guarding it. As the geologist (along with his figure skater girlfriend) are trying to ski to safety, the monster attacks again and kidnaps the helpless woman. What is this creature, and can it be stopped?
