Sand Serpents

On a final mission in Afghanistan, a small U.S. military unit confronts an astonishing, new enemy: a legion of prehistoric, six-story-tall sand serpents unearthed from their pit a thousand feet below ground. With the help of an Afghani refugee, Lieutenant Stanley (Jason Gedrick) leads his tiny band of soldiers on a terrifying invasion deep into the desert's vast underground tunnels for a war against a terror they never imagined.
