At the start of his journey, Attenborough meets some of the people and animals that have made their home along the river in Zambia. He is invited to witness the Kuomboka festival, featuring the Litunga, chief of the Lozi people of western Zambia, and his people. In the festival they migrate from Lealui to Limalunga, before Lealui is flooded by the Zambezi. The spectacular ceremony consists of a fleet of barges, many containing the Lotunga’s possessions, making the journey up the river accompanied by heavy drumming of the royal Maoma drums. Other highlights include David Attenborough joining the Litunga as he opens the court and presides over the inauguration ceremony.
