In Depth:  Dayna Curry & Heather Mercer with Stacey Mattingly

When Dayna Curry and Heather Mercer arrived in Afghanistan, they had come to help bring a better life and a little hope to some of the poorest and most oppressed people in the world.

Within a few months, their lives were thrown into chaos as they became pawns in historic international events. They were arrested by the ruling Taliban government for teaching about Christianity to the people with whom they worked. In the middle of their trial, the events of September 11 2001 led to the international war on terrorism, with the Taliban a primary target.
