In the "World's Untold Stories: Innocence for Sale," Aaron Cohen and CNN go undercover in Cambodia. The program vividly depicts the abject cruelty, heartless abuse and dehumanizing condition of children sold into sexual slavery, often by their parents. Once imprisoned, pedophiles who travel to the country from all parts of the world can pay roughly the same cost as a round of drinks for sex with a child. The documentary will enlighten and inspire new conversation about the challenges currently preventing aid workers and authorities from winning the battle in the struggle to free children from this most despicable form of modern-day slavery.
