Cécile is travelling in northern Benin. She happens to cross the path of a young African mother who abandons a baby in her arms... Cécile is going to adopt this rejected child. She accepts this adoption the way one would accept an "accidental" pregnancy. She cannot resist. She decides to keep him and raise him alone. She names the baby Lancelot. The story of this adoption is going to intertwine with Cécile's personal history with men and with her own mother. It is also going to open her up to another world, in the strongest sense of the term. In seeking to contact Lancelot's biological parents seven years after he was abandoned, Cécile discovers the incredible secret story of this child that has become hers.
