After detecting heat emanating from an ancient pyramid buried deep within the ice caps of Antarctica, the billionaire industrialist, Charles Bishop Weyland, and his team of scientists arrive on the icy continent. At first, this unexpected discovery fascinates them; however, once inside the complex network of cavernous, technologically advanced chambers, the intruders will soon come to realise that this intricate pyramid is not the work of the human intellect. Suddenly, the walls start to move, trapping the explorers. Now, as three young and armed-to-the-teeth Predators enter the dark temple of adjudication for their rite of passage, aggressive endoparasitoid Xenomorphs, or Aliens, start flocking into the ancient structure, and the humans become caught in the middle. Who shall live and who shall die in the ultimate battle between Aliens and Predators?
