A five part series of stories following family members who are reunited after separation through family circumstance, tragedy or conflict.
As well as hearing the emotional stories of people who have been searching for others for many years, we also hear the stories of the organisations who help them - including the Red Cross, Salvation Army and Missing Person's Bureau.
The internet has increased the possibility of finding people through social networking and other websites - such as a site set up recently by Missing Person's Bureau and featuring details of unidentified bodies.
The stories have a range of outcomes, not always happy.
Episode 3 (of 5): The Mother's Story
The work of the Red Cross Tracing Service reuniting families across the world following conflict or natural disaster, featuring an interview with Head of the Tracing Service Nev Jefferies and the emotional airport reunion of a mother and her two children from the Ivory Coast.
