The Descent

Six friends on a caving expedition get trapped deep underground and discover they are not alone in this visceral, claustrophobic horror.

One year after a tragic accident, six girlfriends meet in a remote part of the Appalachians for an annual extreme outdoor adventure, this time exploring a cave hidden deep in the woods. Far below the surface of the earth, disaster strikes, and there's no way out. But there is something else lurking under the earth.
