Came across this from a friend (cheers Luke) the other day. Haven't seen it yet, but apparently there's a screening at Citipointe church, Mansfield on November 5th. (I hear $10pp with proceeds going to aid work amongst sex trade victims)
Apparently it's got an R rating, so is probably going to be pretty intense. This trailer isn't graphic though, so definitely check it out.

Definitely an issue worth praying about and increasing public awareness of.
