A UFO crashes near an isolated military base in the far Arctic. Scientists recover the craft's now-frozen alien pilot and take it back to their base. While debating whether to study the alien, try to communicate with it or kill it, the pilot awakens--and the scientists' question of if it is friend or foe is quickly answered. Now, trapped in a frozen wasteland with an unstoppable, nonhuman creature that sees them as prey, the small band of scientists come face to face with The Thing.
