A group of special forces led by Lieutenant Richard Stanley (Jason Gedrick) arrives in Afghanistan in order to deal with the Taliban for their final mission before heading home to the states.

It chases the group back to the original building where they were captured, but the worm eats Sergeant Wilson (Chris Jarman) in the process.

In a ravaged refugee camp, the group acknowledges the actions of Taliban from information provided by a survivor, Amal (Imran Khan), Isla's father.

He and his daughter decide to join the group of soldiers, but fail to convince the other women there, who wish to stay and wait until Taliban give them back their sons, including Isla's brother.

Failing to carry him all the way back, the group has to abandon him; as he dies a worm eats him - in the process, Richard uses a grenade to blow up the creature.

The group reaches a tunnel, which according to Amal, can lead to the other side of Taliban's camp where they can call for choppers and supporting troops.
