THE THING FROM ANOTHER WORLD

In Anchorage, journalist Ned Scott, looking for a story, visits the officer's club of the Alaskan Air Command, where he meets Captain Pat Hendry, his co-pilot and flight navigator. General Fogarty orders Hendry to fly to Polar Expedition Six at the North Pole, per a request from its lead scientist, Nobel laureate Dr. Arthur Carrington; Carrington has radioed that an unusual aircraft has crashed nearby. With Scott, Corporal Barnes, crew chief Bob, and a pack of sled dogs, Hendry pilots a Douglas C-47 Skytrain transport aircraft to the remote outpost.

Upon arrival, Scott and the airmen meet radio operator Tex, scientists Dr. Chapman and his wife, and colleagues Vorhees, Stern, Redding, Stone, Laurence, Wilson, Ambrose, and Carrington. Hendry later rekindles his romance with Nikki Nicholson, Carrington's secretary. Several scientists fly with the airmen to the crash site, finding a large object buried beneath the ice. As they spread out to determine the object's shape, they realize that they are standing in a circle, outlining a flying saucer. The team attempts to free it from the ice with thermite, but a violent reaction with the craft's metal alloy completely destroys it. Their Geiger counter, however, detects something buried nearby: a frozen body. It is excavated intact in a large block of ice and flown back to the base as an Arctic storm closes in on them.

Given the discovery, Hendry assumes command of the outpost and, pending radio instructions from General Fogarty, denies Scott permission to send out his story and refuses the scientists' demands to examine the body. Tex sends an update to Fogarty, and the airmen settle for the storm. A watch is posted; relieving the first shift, Barnes is disturbed by the creature's glare through the clearing ice and covers it with an electric blanket he does not realize is plugged in. The block slowly thaws and the creature, still alive, escapes into the storm. It fights with the sled dogs and kills two, but loses most of its right forearm.

An airman recovers the stump after the attack and the scientists examine its tissue, concluding that the creature is an advanced form of plant life. Carrington is convinced of its superiority to humans and becomes intent on communicating with it. The airmen begin a search, which leads to the outpost's greenhouse. Carrington stays behind with other scientists, having noticed evidence of alien activity there. They discover a hidden third sled dog, which had been bled dry, revealing the creature as a vampire that feeds on blood. Carrington and the scientists post a secret watch of their own, hoping to encounter it before the airmen do.

The next morning, the airmen continue their search. Tex informs them that Fogarty is aware of their discovery and demands further information, now prevented by the fierce storm. Stern appears, badly injured, and tells the group that the creature has killed and bled two scientists. When the airmen investigate, they are attacked, but manage to barricade the creature inside the greenhouse. Hendry confronts Carrington and orders him to remain in his lab and quarters.

Carrington, obsessed with the creature, shows Nicholson and the other scientists that he has been growing small alien plants from seeds taken from the severed arm and feeding them with the base’s blood plasma supply. Hendry discovers the theft when plasma is needed to treat Stern, which leads him to Carrington. Fogarty transmits orders to keep the creature alive, but it escapes from the greenhouse and attacks the airmen in their quarters. They douse it with buckets of kerosene and set it aflame, forcing it to retreat into the −60 °F (−51 °C) storm. After regrouping, they realize the creature has sabotaged the base furnaces’ oil supply, plummeting temperatures indoors. They retreat to the station's generator room to keep warm, and rig a high-voltage electrical "fly trap". The creature continues to stalk them. At the last moment Carrington pleads with it, but is knocked violently aside. The creature walks into the trap and is electrocuted. On Hendry's order, it is reduced to a pile of ash.

When the weather clears, Hendry and Nicholson are careening toward marriage, and Scotty is finally able to radio his "story of a lifetime" to a roomful of reporters in Anchorage. He ends his broadcast with the warning: "Tell the world. Tell this to everybody, wherever they are. Watch the skies everywhere. Keep looking. Keep watching the skies...".

The alien organism is ultimately destroyed by the combined efforts of the scientists and Air Force officials, ensuring the safety of the outpost.

The film’s climax emphasizes the necessity of cooperation between science and the military in the face of an unknown threat. The destruction of the alien reaffirms human ingenuity and resilience, while the film’s final warning—'Keep watching the skies!'—captures lingering anxieties about what might still be out there.
