Set in the Ardèche river Gorge (France), thirty-six thousand years ago, Traces follows a tribe as they prepare for a big hunt, with the return of the buffalo imminent. As Gwel prepares his group of hunters for the task ahead, Karou the Painter and his apprentice Lani travel to a great cavern, where they will capture the event in detailed wall drawings, believing that what they paint will influence the outcome of the hunt.
