This is the story between sky and earth, of a group of "crazy climbers" who have managed to make a very difficut job easier with their enthusiasm and dreams. Three years ago they decided to work together: they are called Versant. Working day and night, they find themselves in the most unexpected situations. This is what make their work as skyscraper window cleaners seem a game. An exciting and dangerous game, which has strict rules, severe training, but also a lot of cunning and imagination. Yannick, Jean Rene, Jean Philippe and the others pass from the Centre National d' Industries et des Techniques to the Cathedral of Limoges, to the new Bastille. Their itinerary passes over the most daring modern and ancient architecture.
