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.

We meet a Texas woman whose donated breastmilk helped thousands of premature babies. Also: surviving thirteen days alone in Australia's mountains; a chess playing NBA star; and appealing for friends to tackle loneliness.

Sahar Zand follows young Hindu activists Banamali and Sukanto, who are documenting the violence they say authorities and media are ignoring. She joins them as they respond to a new attack on a Hindu-majority village, where a mob set fire to a yet another building. The attacks are not just aimed at buildings. Sahar meets victims, including an elderly village doctor recovering from an attempted murder and a grieving mother whose 14-year-old son was killed trying to escape the country. In a tense interview, Sahar confronts Mahmudul Hasan Gunovi, a far-right Islamist leader accused of fueling the violence with his inflammatory rhetoric. She experiences the violence first-hand during a volatile encounter when Banamali and Sukanto visit a sensitive site, where a Hindu crematorium has recently been destroyed, and a make-shift mosque built on its ruins.
