Daniel Piron, a former political columnist and left-wing activist, is "promoted" in a road safety program during which he runs into Sacchi. Sacchi had made headlines 25 years earlier by hijacking a school bus to denounce social injustices on the air. Sacchi was arrested before he could get on the air. Piron, for whom Sacchi remained a revolutionary icon, wanted to find the protagonists of this hostage-taking to make an ambitious film on the evolution of society. Unfortunately, Sacchi is no longer the revolutionary he was then. Piron has to manipulate reality and becomes the new hostage taker in a reenactment that goes haywire.
