"The Child Sex Trade in America"

Libby Spears goes undercover in southeast Asia to infiltrate the vast network of people involved in human trafficking (specifically, sex slaves), and discovers that not only are a significant number of its victims children, but also that the United States is one of the industry's biggest customers. When she returns home to learn more, she discovers the roles that the educational system and law enforcement have played in keeping the issue off the radar.
