Many CNN viewers know him as Mira Sorvino's guide in "Every Day in Cambodia," the 2013 CNN Freedom Project documentary that fixed a spotlight on child sex trafficking in the country.
American activist Don Brewster has dedicated his life to saving Cambodia's children. As the founder of Agape International Mission, he has helped rescue hundreds of girls from sexual slavery.
In Hong Kong, I talked to Brewster about how he tracks down Cambodia's enslaved girls, helps to rebuild their lives, and equips local communities to join the fight against the despicable trade.
Brewster also tells me about the impact of the Freedom Project documentary, and how it has led to justice for some of the girls in Cambodia.
