korea we're covering missile launches or the recent nuclear tests. we're driving through the city and you look out the window and you think, gosh, we could just pull over. that would be such a great story. i would love to ask these people what they're doing. this documentary is a chance for us to do that. yes, we were under the control of governmentminders. they supervise that we're doing and restrict what we can film. but there are opportunities that we have never had before, to stop the van and just jump out and talk to the people. this was not preplanned, not staged. those are some of the best highlighted in this hour. i want to show you some. in north korea, government minders watch our every move and restrict what we can film. even if this is what we want to see. high school students horses around at the beach. i can't help but wonder, what do they actually know about america?
