It's a growing crime in the United States - young girls, some from traditional, stable families, are lured into the sex trade and end up being bought and sold by men.

Their chilling stories are the focus of a new ad campaign by Shared Hope International.

The group's 15-second digital ad in Times Square will soon reach primetime television viewers.  The spot tells the story of Brianna, a normal American teenager who was tricked by a man pretending to be her friend.

He subtly lured her in while she waitressed at a restaurant, promising her a better life.

But those claims quickly turned into control and manipulation. Before long, Brianna severed ties with her family and the man put her to work in a strip club.

She was nearly sold into prostitution, but Shared Hope stepped in to help her parents look for her and bring her home.

President Linda Smith said her group is using stories like Brianna's to educate young women and their families about the danger of human trafficking.

Linda Smith talked to CBN News earlier this month about the reality of modern-day slavery and her group's efforts to spread awareness.  Watch the entire interview below.
