While searching for the Taliban in war-stricken Afghanistan, a platoon of U.S. army soldiers comes upon a mysterious cave. Thinking that they might find what they are looking for inside, they enter, only to trap themselves. Soon, they realize that they are not alone and that the cave is housing a dangerous human-consuming monster. With this creature aggressively tailing them and picking them off one by one, they must fight back to end its reign of terror once and for all.
