In Freetown, Sierra Leone, we join a group of African-Americans who have all taken a DNA test and discovered their ancestors came from this country on the West Coast of Africa, before they were trafficked to the US and enslaved. Over their two week trip, we explore the bustling city of Freetown, a very different experience to the US. They travel to remote villages where their ancestors may have lived. Here they are each adopted by a local family and given a traditional name according to the ethnic group indicated in their DNA test. There is also a boat trip to Bunce Island, where they find the ruins of a slave fort where men, women and children were held captive in appalling conditions. And we meet other returnees who have come back to Sierra Leone to make a difference.
