The International Network of Consecrated Life Against Trafficking in Persons, and it consists of 1,100 sisters operating in 80 countries, but there are plans for expansion into 60 more countries. 

This word comes of the group's growing status comes from John Studzinski, an investment banker and philanthropist who chairs Talitha Kum. The group estimates that about 73 million people are trafficked in some form, and that 70-percent are women and half are under 16 years old.

To fight this, the religious sisters often dress as prostitutes and integrate themselves into brothels. 

"These sisters do not trust anyone. They do not trust governments, they do not trust corporations, and they don't trust the local police. In some cases they cannot trust male clergy," Studzinski said. 

"They work in brothels. No one knows they are there."

Talitha Kum also raises money to buy children sold into slavery by their parents and then set them up in a network of homes around the world. 

"I'm not trying to be sensational but I'm trying to underscore the fact this is a world that has lost innocence ... where dark forces are active," said Studzinski
