In the winter of 1982, a Norwegian research team discovers a spacecraft and its shape-shifting occupant, which had become buried in the ice for roughly 100,000 years. They take the ice-encased creature back for further studies, whereupon it is accidentally revived, escapes and begins assimilating and killing off the crew. The outpost is eventually destroyed in the ensuing chaos and the two survivors from the camp chase the remaining creature (now imitating an Alaskan Malamute) to a nearby American outpost - U.S. Outpost 31.
