The plight of child sex slaves has been well publicised but seldom do we get to see inside their nasty world. Recently however, an undercover film crew did just that. They gained rare access to Diana and Lina, two teenage prostitutes at a brothel in Batam. Focusing on the girls' plight and the mission to save them, they filmed every event leading to the girls' rescue. It's a confronting and harrowing expose of young children lured into a life of prostitution.
