It is said that somewhere in the bowels of the district of La Défense, a monster slumbers, forgotten by everyone. It occupies a secluded room in the basement of this business district dedicated to the world of finance. This gigantic creature would be the masterpiece of a man: the artist Raymond Moretti from Nice in France. It is said that the painter sacrificed everything for this work of art. Why did he prefer to consecrate his life to it rather than to the brilliant career that presented itself to him? Why did he leave his strange offspring dragging him inexorably to the depths of La Défense and oblivion? This documentary addresses the story of an artist and his sacred work.
