A group of friends fight for their lives against the lethal and ravenous creatures lurking beneath the Earth's surface.

Though they fought countless battles in Iraq, these friends never knew real fear until they went underground.—Anonymous
The movie left me with lots of unanswered questions, wishing there was a movie to explain this movie.
