Tribal identities continue to play a role in social and political rifts  in many parts of the world, even erupting into outright conflict. In the  southern African nation of Zambia, a younger generation now attempts to  bridge the gap between different tribes. But long-held stereotypes make  it difficult for Zambians to discard their tribal identity entirely.  Zambian journalist and radio host Angel Bwalya Kasabo introduces us to  two Zambian families who come from different tribes–the Tonga and  Bemba–that have intermarried. These Zambian families have crossed not  only tribal borders, but their own borders of prejudice. Their  experiences can bring understanding about how to break through tension  and misunderstanding between families in a polarized society.
