Mass is a dance filmed in a sequence shot, including forty amateur dancers. Crowd images are more and more recurrent and symbolize the current upheavals, evoking in turn festivals, migrations, demonstrations, gatherings or even the daily life of metropolises. So we work on the mass, with all the intoxication it can inspire. We confront the individual with crowd movements, in order to observe the way in which he resists or allows himself to be immersed.
