Jairo Zavala, a Spanish singer-songwriter with African and South-American roots and member of the indie-rock band Calexico, is invited by Ángel Carmona to participate in a series of radio interviews. As an omniscient narrator, Carmona's radio voice strings together Zavala's adventures through Senegal following the trail of a particular griot: Lamine Konté. On his journey from Dakar to Casamance, he witnesses the return to the stages of an ''afromandinga'' music band, cast into oblivion 30 years ago, the Dieuf-Dieul from Thiès. There, he learns about the African music genres that went to America only to return home, genres such as soul, rock, rumba, etc., and Casamance's griot mysticism, Land of Kings, where Zavala seeks inspiration in order to compose the journey's soundtrack itself.
