chunk: In the Antarctic, a Norwegian helicopter pursues an Alaskan Malamute to an American research station. Upon landing, the passenger accidentally drops a thermite charge, which destroys the helicopter and kills the pilot when he tries to retrieve it. The passenger pursues the dog, firing a rifle, until he is shot dead by Garry, the station commander. The Americans send a helicopter pilot, MacReady, and Dr. Copper to the Norwegian camp for answers, but they find only a charred ruin. Inside, they find a corpse with its throat and wrists slashed in the radio room. Outside, they discover the burned remains of a humanoid corpse with two faces, which they bring back along with some video tapes. Their biologist, Blair, performs an autopsy on the corpse, finding a normal set of human internal organs.
