Private Bowe Bergdahl left his Army post in Afghanistan in 2009, intending to hike about 20 miles to a larger command center and trigger a "DUSTWUN" manhunt. In telephone conversations with Mark Boal, a documentary film maker, Bergdahl said he wanted to report poor leadership at his post and air grievances, but enemy fighters captured him within hours of his disappearance. Sarah Koenig will be using more of the 25 hours of recorded conversations between Bergdahl and Boal to tell his story.
