Sex for Sale (S01E02)

The illegal, multibillion-dollar global sex trade includes brothels, massage parlors and online escort agencies and is one of the oldest professions. Take a look inside this illegal trade where pimps treat women as commodities — bought and sold, used and abused, then discarded. Go undercover with cops in Oakland posing as prostitutes to catch "johns" looking for sex. Meet Kassandra, a "renegade" who escaped her pimp and now is an independent sex worker. Go inside a New York City brothel, where the madam Princess runs a mini sex dynasty. And hear from a woman who escaped the industry, but now, after years of abuse, is still struggling to piece her life back together. (National Geographic)
