"Didy is everywhere”, says Gaël Kamilindi at the start of his film. And yet, the emptiness is immense. In order to fill this void, he sets off for Rwanda, accompanied by François-Xavier Destors, in search of his mother Didy, who died when he was five. Heartrending archival footage mingles with survivors’ memories to paint the portrait of this woman, thus setting in motion the process of mourning.
