Of Afro-Caribbean origin, raised in the suburbs of Paris, Julia (Julie Ledru) is passionate about (riding) motorcycles, and her talent for driving them is surpassed only by that of stealing them.

In order to earn a place in the world of underground motocross racing and live completely by its rules, she puts all her skills at the disposal of the organizing gang. But the initial hostilities, caused by the perception of her supposed femininity, do not disappear altogether, but only return in other forms.

Combining documentary social observation with elements of fantasy, the film aims to be an ode to freedom and nonconformity preserved at all costs.
