of the deal. The detainees, living in luxury. Martha Raddatz tracking all of the latest developments in Washington. Good morning, Martha. Reporter: Good morning, robin. This is a Taliban propaganda video. It is narrated with rants throughout. But it is the first time the public has seen bergdahl's face in more than three years, when the last hostage video was released by the Taliban. This one, about eight minutes of video with a dazed and palebu bergdahl, walking to freedom. He sits in a truck, local dress, blinking rapidly, as if coming out into the light for the first time. There are more than a dozen Taliban watching from a hillside. And those surrounding him, armed with ak-47s and rocket-propelled grenades. A white, Taliban flag, held as a signal to U.S. Forces. Above, American aircraft circles. Bergdahl looks skyward, as the Taliban shouts, long live the Taliban. Long live mullah omar. The helicopters approach, as the Taliban speaks to bergdahl, who remains expressionless. He is warned, don't come back to Afghanistan. Don't come back again. You won't make it out alive next time. The exchange is swift. Bergdahl is walked forward, carrying a small, plastic bag. The special operations approach. One almost certainly an interpreter. A quick handshake and a pat-down of bergdahl's back, to check to see if he was ampled or explosives placed on his body. He walks steadily forward. But before getting into the helicopter, another body check, to see if it is safe to put him onboard. The extraordinary exchange, all over in 90 seconds. Safely onboard, we know bergdahl broke down in tears, with the realization he was freed. But how he was taken into captivity five years ago and the terms of his release, are still creating controversy. ABC news being told by senior officials and soldiers with whom he served, that he walked away from his base willingly. The army is now preparing an investigation to get his side of the story. Bergdahl's parents have not commented this morning about the video. But they are surely relieved to see that he appears to be walking with ease. But officials say he has a long road ahead. And still, there is no sign of when he will be returned home. The physical signs. And the questions about his mental health. Martha Raddatz, leading us off. Thank you.
