During a training exercise in an abandoned open-pit mine, a crew of Canadian astronauts are interrupted by an Atikamekw elder, who asks them to deliver an important message to the spirit of his community on the moon.

Manawan, 1977. A vehicle falls into a river near a Native community. Two Quebecers managed to escape, but five Atikamekws lost their lives. While the police conclude that it was an accident, the victims’ families are left with unanswered questions. A historical, poetic and choral tale, Soleils Atikamekw is inspired by the dreams, impressions and memories of the relatives of the five victims. In an intimate, humanistic approach, the filmmaker involves the families both in front of and behind the camera. Documentary and fiction come together in a deeply moving film about grief, injustice and memory.
