A team of US Special Ops forces is dispatched to a remote mountain region of Afghanistan with orders to locate an influential Muslim cleric. While on the mission they find themselves lost in a Middle Eastern 'Bermuda Triangle' of ancient evil and faced with an enemy that none of them could have imagined.
Royal Air Force pilot Lt. Kate Sinclair is on her final flight mission when her jet is shot down over one of the most dangerous rebel strongholds in Afghanistan. She finds refuge in an abandoned underground bunker where deadly man-made creatures known as Ravagers — half-human, half-alien, and hungry for human flesh — are awakened.
Jason Gedrick and a small group of Marines are stranded in the remote Afghan desert. But it ain't the Taliban that's worrying them, it's these giant refugees from Tremors. In fact the big worms prove to be an ally of sorts by doing better against the Taliban than themselves but battling these enemies is something not covered in their training.
Following the 9/11 attacks, the war on terror against Afghanistan continues. With the Taliban insurgents hiding out in the mountains however, they become increasingly difficult for the US military to engage. The solution is to try and flush them out by adding low level chemicals to the water supply. Little do the USA know however that enemy scientists have adapted the chemicals to make their own formula, one that can bring the dead back to life.
