This is a collection of two documentaries by Henry Brandt digitally restored by the Cinémathèque suisse. While "Les nomades du soleil" follows the nomads of the Wodaabe and their herds in Niger in 1955, "Les hommes des châteaux" shows the everyday life of the sedentary tribe of the Batammariba in the north of Dahomey, today's Benin. Unique contemporary testimonies of ways of life and cultures that are disappearing.
