Hidden cameras expose a cruel "flesh trade" in which thousands of women from poor countries are lured to Europe for jobs that turn out to be in the sex industry. In strange cities, and without money or passports, they are tricked and trapped into unwilling prostitution, and many fear shame, debt and reprisals if they speak out.
One woman who expected to be employed as a barmaid says: "On the first day I knew what they had told us in Poland was one big lie. We couldn't move because we had almost no money and no passport. We were just scared really. The boss looked as if he could kill you if something wasn't going the way he wanted."
Producer Christopher Terrill and associate producer David Perrin went under cover to investigate, following the story from the recruitment of women in the Caribbean to the notorious vice clubs run by a Dutch-based gang, alleged to be the biggest of the sex syndicates.
