Twenty-one-year-old Katia...left home on what she believed would be a trip to buy goods in Turkey, but instead she was sold into sexual slavery for $1,000. In Sex Slaves," FRONTLINE follows [her husband] Viorel on an extraordinary journey deep into the world of sex trafficking to try to find his wife...and then free her from the violent pimp who now "owns" her. Along the way, the production team takes a rare, hidden-camera look at the various traffickers, pimps and middlemen who illegally buy and sell hundreds of thousands of women each year. Lured by traffickers who prey on their dreams of employment abroad, many of the women are then kidnapped and "exported" to Europe, the Middle East, the United States and elsewhere. During this process, they may be sold to pimps, locked in brothels, drugged, terrorized and raped repeatedly. "How much will a girl cost?" co-producer Felix Golubev asks a trafficker in Moldova while posing undercover as an interested buyer from North America. "Five hundred to 600 dollars" replies the trafficker." As Viorel searches for Katia, we learn what she might be enduring from other trafficked women. Twenty-eight-year-old Oksana was sold 13 times over an eight-month period before finally being allowed to return to her native Ukraine. "There were 22 girls in a three-bedroom apartment, and each girl got beaten up at least once a day. One girl ran away and went to the police for help, but she was taken back. Policemenused our services." "Sex Slaves" exposes the government indifference that allows the global sex trade to continue virtually unchecked and what needs to be done.
