In a Parisian apartment, police discover the body of Georges Figon, the man who broke the scandal of the Mehdi Ben Barka affair, and undermined Gaullist power. A year earlier, Figon, tired of dubious deals and petty scams, is looking for a lucrative job. Close to the "middle" since his years in prison, he is given a big assignment: to produce a documentary about decolonization, written by Marguerite Duras and directed by Georges Franju, with the help of famous Moroccan dissident, Mehdi Ben Barka, who has been hired as an historical consultant. The film project is a trap.
