A group of nuns are dressing as prostitutes to help save the lives of human sex trafficking victims.

There are a network of nuns, called Talitha Kum, who are working undercover to help out victims of human trafficking as well as children that have been sold into slavery. The group is working worldwide -- in about 80 countries to be exact -- and are growing. The group hopes to expand to about 140 countries to help with the human trafficking problem worldwide.

Talitha Kum consists of about 1,100 religious sisters that undercover in brothels to help free sex trafficking and buy children sold into slavery.

John Studzinski is an investment banker and philanthropist who chairs Talitha Kum and explained the purpose of this group in a speech on Nov. 18.

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

Talitha Kum, which means "arise child" in Arabic, was founded in 2004. Nuns dress up as prostitutes and even walk the streets in an effort to stay incognito while working to save lives. The group also works to raise money to help buy children and free them from slavery.
