This is the story of a ball. A grand ball. Every summer, more than two thousand people come from accross Europe to dance together, dance even more, during seven days and seven nights, in the countryside of France. A joyful crowd of men and women from all ages, speaking different languages, beginners, virtuosos, enthusiasts. A crowd that reveals how different it is when we dare look into one's eyes, when we dare touch one another. And how life pounds.
