We go inside Bangladesh’s biggest brothel, a town where 1,500 women work as prostitutes, some as young as 10 years old. In a ramshackle maze of dirty alleyways, women and girls work day and night in tiny cubicles, meeting the men who pour in from the nearby highway. Many of the prostitutes have always lived there; some were sold into prostitution by their families, and others were abducted from their villages.
