 Set in the early 21st century on Earth, Charles Weyland, an industrialist billionaire, leads an archaeological expedition in Antartica. Using thermal imaging satellites, Weyland believes to have discovered the ruins of an ancient pyramid temple that predates the Egyptian and Aztec pyramids buried under the ice. Once inside, the team finds the remains of humans with holes in the rib cage and the remains of facehuggers, meaning that the possibility of the temple being uninhabited is very unlikely. To make matters worse, a group of teenage Predators are coming to the temple to perform a coming-of-age ritual that involves fighting to the death with the aliens. Soon, it becomes clear that only one species is getting out alive.
