Exodus Cry is working on a documentary called Nefarious: Merchant of Souls. From their website:

Nefarious is a controversial documentary exposing the undercurrent of injustice beneath the surface of sex-tourism. Millions of women and children around the world are increasingly become the expendable pawns of a burgeoning business catering to the demand for illicit sex. These women and children are dehumanized and exploited while mainstream culture remains complicit in their demise. Benji Nolot goes undercover to reveal the plight of the exploited and uncover the hypocrisy and complicity of cultures around the world that foster this industry, as well as offer an unexpected hope for comprehensive change.
