TERROR IN THE MIDNIGHT SUN

While traveling in Sweden, Olympic skater Diane Wilson meets up with her uncle, famous geologist Dr. Vance Wilson (Robert Burton), who has come there to help investigate the recent landing of what appears to be a large meteorite. Diane is courted by her uncle's associate, Dr. Erik Engstrom (Sten Gester), though she aggressively plays hard-to-get while they are skiing, at one point grabbing his skis and leaving him to walk back all the way to the hotel. A romance slowly begins, and eventually they are interrupted by the news of a large herd of mutilated reindeer in Lapland. Both scientists immediately fly there, far north in the Arctic mountains of Lapland, near the site of the meteorite crash. To the irritation of both scientists, they discover Diane has stowed away aboard their aircraft. When they arrive, the meteorite is actually determined to be a round alien spaceship, and she suddenly realizes just how dangerous a decision she has made.

An enormously tall, hairy biped creature, with powerful jaws, tusks, and large round feet, under the control of three humanoid aliens in the spaceship, comes out of nowhere and begins menacing the scientists and the native Laplanders. The tall beast destroys the scientists' aircraft, killing the soldier guarding it, and begins tearing apart Laplander houses with its bare hands. As Dr. Engstrom and Diane are trying to ski away to safety, the hairy monster attacks again and is able to capture Diane. She screams and faints.

Meanwhile, a search party has been formed, now carrying torches as night begins to fall. They hear Diane's screams and go toward the sound. Dr. Engstrom arrives and watches as the hairy monster carries her off. He hurries toward the torch-carrying Laplanders and tries to alert Dr. Wilson, who is with them, that the creature now has Diane. Carrying her to the snow-buried alien spaceship, the extraterrestrial monster suddenly begins displaying tenderness toward his captive, a result of mind control exerted over the creature by the humanoid aliens. She runs into an adjoining ice cave and screams and faints again when the aliens come near. The aliens leave the cave and see the mass of lighted torches coming their way. The hairy monster picks up Diane and heads away from the buried spaceship.

The Laplanders give chase and are finally able to confront the huge creature, who is now standing with its back to the edge of a deep snow cliff. Angry villagers begin throwing their fire torches, and the tall monster carefully places Diane on the ground, where she is able to roll several feet away. More torches are thrown and the hairy creature catches on fire, falling backward fully engulfed over the cliff to a fiery death down below. The aliens take off in their spaceship, returning the very way they came. Diane and Erik walk off into the midnight sun together.

The villagers and scientists confront the alien-controlled monster, ultimately setting it on fire and sending it over a cliff to its death. The aliens depart in their spaceship, and Diane and Erik walk off together into the midnight sun.

The climax sees collective human effort overcoming the alien menace, suggesting that even otherworldly threats can be vanquished by unity and courage. The film closes with Diane and Erik's symbolic walk into the never-ending daylight, hinting at hope and renewal after chaos and terror.
