Watch VoirFilms. A moving, feature-length documentary shot on three continents, and amongst the most ambitious factual programmes on the BBC in recent times. Motherland used genetics to enable members of the African diaspora to trace for the first time their African ancestry. Three Black Britons become the first people ever to uncover what Alex Haley, author of Roots, could only dream of - to "go back" to Africa and reconnect with the precise population groups from which their ancestors were separated by slavery.
