Motorbikes are the new horses and not exactly legal motocross races and stunts are the new rodeos. In this film, Julie Ledru is Julia, a woman with a hard shell and no fear, marked by her passion for motorcycles, their speed, and the feeling of freedom they provide. But the ultra-masculine world of the Paris suburbs that Julia wants to inhabit requires increasingly risky tests and her place in this community is not an easy one to secure.
