This unique "road documentary" finds Youssou N'Dour, a vocalist from Senegal, undertaking a transcontinental journey and traveling the routes of 19th century American slaves. Guided by the blind Tunisian pianist Moncef Genoud, N'Dour gravitates from Atlanta to New Orleans to the Big Apple, then leaves the United States for Europe and visits Bordeaux, France, and Luxembourg, meanwhile performing his jazz- and gospel-influenced songs constantly. The film witnesses N'Dour rehearsing with an extensive series of musicians and preparing for a final concert in Gorée. That locale (an island off of Senegal's coast) attains particularly strong thematic relevance, geographically situated as it was at the crossroads of slave routes between Europe and Africa.
