Alain Kassanda's debut film begins as a self-examination. How well does he know his grandparents? What does he know about his native Congo, which was partly imposed on his identity by colonizer Belgium? And what does he know about himself with that? In Colette et Justin, he travels through time and his personal family history - in which he also beautifully brings the history of postcolonial Congo to life. He lets his grandparents look back on their lives, from their youth and first meeting to a complex political period. The Congo's first independent years pass by as a layered history, in which good and evil intertwine and Justin was assigned an important role.
