Sex tourism may be one of Thailand's most profitable industries. Many of the foreign men who enter the country as tourists come for sex; the demand is high, and the market is massive. Servicing this demand are women trafficked from all over the world, including those lured to Thailand by a vicious Thai-Uzbek ring. Most Uzbek women who work in the industry come to Bangkok out of financial desperation; they believe they'll get good jobs, but they end up as slaves.
