A film of Chris Marker and the broadcasting(audiovisual) confederate Group - CFDT(FRENCH TRADE UNION)... For the centenarian of the law of 1884, which we agree to take for point of departure of the labor union, CFDT(FRENCH TRADE UNION) confided to Chris Marker the realisation of a film dedicated to hundred years of syndicalism in France. Chris Marker plans the question in the future and imagines a television news of 2084 for the anniversary of the second centenarian and three possible scenarios: the grey hypothesis, that of the "crisis", " a fearful society which hums and gives itself false safeties in the hope of a balance always questioned "; the black hypothesis, " a world where the technique took the place of the ideologies "; the blue hypothesis, finally, that of the dream and the imagination.
