A group of scientists uncover an alien body in the Arctic that attacks them one by one. Kate is a paleontologist hired by Sander, a Norwegian scientist on expedition to the Arctic who has found an alien craft and life form trapped in the ice. Kate and her assistant Adam arrive at the site accompanied by American soldiers/pilots Carter and Jameson, and meet the rest of the team made up of Norwegians who hold camp there.
Sander has the alien body extracted, but still encased in a frozen block of ice. The alien is returned to the camp for study and observation. Sander has also gone ahead and drilled a hole into the ice to get some samples from the being, something that Kate was truly against since the creature might release something unsafe. As the group retreat to the common room, the alien breaks free from the ice, killing the camp dog.
Jameson gets a good look at the creature, a crustacean-looking slimy alien with lots of arms. He alerts the rest. The alien then goes on a killing spree, attacking two men, killing one by eating it. The group is able to sever a huge part of the creature and takes it back to the lab to study it. They learn that the thing copies its host, however, anything non-biological such as metal (as was the case of the last guy who was killed whose metal tooth fillings were left behind), is spit out. They also deduce that anything that comes into contact with the thing is "infected," thus, no one can be trusted.
Sure enough, when Kate least expects it, the only other woman in the camp starts morphing into a creature and attacks Kate. Adam, and the mechanic Lars fend it off with a flame thrower. Meanwhile, the two American pilots, after being feared dead from an accident appear. They are locked up. Tensions and suspicions arise, prompting Kate to inspect people's mouths for their tooth fillings. Four people are suspected of being infected, including Sander and Adam. Later the two Americans escape, they attack Lars. Everyone is held hostage.
Soon, we learn that the thing has infiltrated Edvard, Jonas, Adam, and Jameson, who attack the remaining survivors. The lab is blown up and Sander is infected. He escapes out in the ice heading for the alien ship. Kate and Carter chase him. With a grenade, Kate blows up the ship, killing Sander.
With just Kate and Carter left, Kate kills him noticing that his earring is missing. Lars apparently has survived and is rescued by a chopper. They see the resurrected dog as it sprints onto the ice field. They track it down.
Best part of story, including ending:
It's the prequel to the 80's movie starring Kurt Russell. Giving us the backstory to that film.
Best scene in story:
When Kate turns around slowly to see Juliette morph into the disgusting alien.
Opinion about the main character:
Kate reminds me a lot of Sigourney Weaver in the Alien movies, she takes charge and fights.
