Main dans la Main plot
Helene attends the prestigious ballet school of the Paris Opera. She shares her life with her old friend Constance. Joachim works for a mirror maker, far away from the bustle of Paris. He enjoys skateboarding and lives with his sister and her husband, who run the local gym. But when their paths happen to cross, it seems as if a strange power is taking them under its spell. Without understanding how or why, they can no longer be separated from each other. It's physically impossible. If one runs in one direction, the other follows. When Helene raises her arm, Joachim's arm goes up with it and when he takes a step along one side, she moves with him, totally helpless.
