Plot synopsis: Usures is a reflection after an encounter with Saïd, a homeless choreographer. His withdrawal from the world translates into an absence from the film. Usures then fills this void with bodies in movement, substrates and bursts of life that embody the emotional states that Saïd goes through in his daily life. The underground corridors, intervals between two worlds, become the scene where bodies reconcile and reclaim the power over their fate.
