On a deserted island near the edge of the Antarctic ice, the largest meteorite ever to fall on Earth has been lying for several million years. Palmer Lloyd, a New York billionaire and famous collector of rarities, decides to add this mysterious alien from the depths of the Universe to his collection. The entire operation to transport a block weighing four thousand tons must be carried out in the strictest secrecy, so that nothing would prevent Lloyd from taking possession of the coveted rarity. However, danger threatens not only from the outside, it lurks in the meteorite itself. Gradually, the members of the expedition begin to understand that it was not they who captured this mysterious ancient object, but it captured them and is not going to let them go alive.
