Youth can be a minefield: drugs, sex, violence, and peer pressure. One group has an extreme way of dealing with it. They call themselves Straight Edge, and while they are being classified as a violent gang in areas such as Salt Lake City and Reno, they aren't like any other gang you know: they reject drugs, drinking, smoking, and even casual sex. They're rebels against a society in which everything goes. National Geographic goes inside this growing youth movement caught between being a refuge for Americas kids and a dangerous gang wanted by authorities.
