Agathe, 18, dreams of change. Gone are her vacations on the rainy beaches of Belgium! She decides to hitchhike down to the South of France, where she'll have many happy and less happy encounters. On the way to Paris, men of various ages offer to shorten her wait by the roadside. Some try to take advantage of her, while another, in a fit of madness, tries to stab her. Despite these assaults, Agathe continues her journey, heading for Valence and then Aix-en-Provence.
