*** SPOILER ALERT ***
It's set in Antarctica, and this scientific team finds these incredibly strange alien creatures that had apparently been trapped in a cave by a rock fall and either starved or frozen to death. They bring one back to camp and dissect it. They are amazed at how well preserved it is- the tissues are so fresh it's as if it had only died a few minutes ago, not thousands of years. Even the fluids are still liquid. Anyway, they go back to the cave- and the rest of the alien creatures are missing. But there are strange tracks leading back towards their camp. Yep, they get back, and the camp is a wreck. But not a brutal wreck- it has been thoroughly searched and looted. And a bunch of equipment is missing- flashlights, portable heaters, fuel, blankets, food, and one of the sleds. The dissected creature has been buried in the snow, and the guy they left at the camp- has been carefully dissected and studied. Turns out they weren't dead- just hibernating. So the two surviving scientists end up tracking these creatures. And they track them to a fabulous but spooky lost city. And once they get into the city, things get even more interesting.
