The search for the mysterious "Afghan Girl," whose haunting, green-eyed gaze captivated the world in a NATIONAL GEOGRAPHIC magazine cover photograph, takes you on a world-wide journey in an attempt to solve the case of a missing person. In January 2002, photographer Steve McCurry, who took the 1984 photograph and who has been searching for the girl ever since, traveled to Pakistan with a National Geographic team to search one last time.

Has the "Afghan Girl" survived? With a lot of detective work and a little luck, the National Geographic team, together with McCurry, finds a woman who could be the "Afghan Girl." How can they confirm that this is the same person as the child photographed nearly 20 years ago? National Geographic uses several methods, including state of the art iris recognition, the FBI facial recognition techniques and the technology used by the National Center for Missing and Exploited Children. Sigourney Weaver narrates.
