This exclusive film highlights the rise of ISIS in Afghanistan at a time when the Taliban is in flux following the announcement of the death of its leader, Mullah Omar, and the threat of a split between the old command, said to be under the influence of Pakistani intelligence (ISI), and younger commanders who reject that influence and are increasingly attracted to the new, more violent brand represented by ISIS.

In it, we see how ISIS is planning for the future by indoctrinating children, teaching them not just the fundamentals of Jihad, but how to use pistols, sub-machine guns and throw grenades.

We join government forces on the frontline against ISIS, who claim this enemy is stronger and more dangerous than the Taliban.

And we talk to the Taliban itself, which seems confused as to why any Afghans would be attracted to a group controlled from Iraq.
