American Call-Girl (2011)

An undercover investigation into the escort industry in Las Vegas, where prostitution is illegal on paper but alive and well in practice, with the industry making use of clever ways for the John to "read between the lines" while everyone else turns a blind eye. With the Internet the backbone of the 21st century sex industry, thousands of escort websites are carefully worded, but if you look closely, many appear to clearly sell sex in a fiercely competitive 'market.'
