A man of images is preparing to make a film and hires a professional casting assistant to help him find, in the streets of Paris, the woman who will become his model, his actress. They are saleswomen, unemployed, students, lovers, unhappy, actresses, seductive or disillusioned. They wonder why, among the crowd, he has chosen them. They are not acting; they live these moments as just another encounter in their lives, with striking freshness and spontaneity.
