there were no embassy officials around to help. this woman has no connection to the u.s. or to the u.s. embassy or a company or contractor, but she is just saying out of mercy, her husband died several years ago, and she is afraid the taliban are going to come, and she is afraid they're going do horrible things to women and children. so she is just here hoping that maybe there is a possibility that she can get a visa for her son. >> reporter: there was a plan for a peaceful transition, a plan for the taliban to enter kabul and then share power with the u.s.-backed government. but there is an old expression in war. no plan survives the first contact with the enemy. as the taliban tightened their noose around kabul, they broke into the main prisons and released thousands of their fighters and thousands of isis extremists.
