The memory of the places where the slave trade and French colonial slavery unfolded for nearly four centuries: ruins, opulent buildings, landscapes imbued with that tragic memory — Ghana, Senegal, Guadeloupe, Martinique, Guyane, Réunion, Haiti, Bordeaux, La Rochelle, Le Havre, Lorient, Marseille, Nantes. By letting the light he captures reach the whole of the film, Philippe Monges turns the drive perforations of the roll into so many black and indelible imprints.
