The episode starts with Palin crossing the Sénégal River, leaving Mauritania and entering the town of Saint-Louis in Senegal. He has left Arab Africa and entered Black Africa, and the French influence, from the colonial past, is strongly felt here. He interviews the artist Jacob Yakouba and his soap-opera-star wife Marie-Madeleine, talking to them about polygamy, which is prevalent here. Palin also visits Gorée Island, the main departure point for black slaves sold to America. Palin moves on to Dakar and watches (and takes part in) a late-night wrestling match, and then talks to the owner of a jazz café. Then he takes the Bamako Express train to Bamako in Mali, talking to a native woman about polygamy along the way. In Bamako he talks to the musician Toumani Diabate. Palin visits the town of Tirelli on the Bandiagara Escarpment where the Dogon people live.
