In the summer, 27 year-old Sam drives towards the south of France in his Ford. He meets Matthieu and his sister Léa and takes them along in his apparently aimless journey.

Throughout the trip, they learn to know, fight and love each other. In spite of a blooming relationship with Matthieu, Sam isolates himself because of his secret: he is headed for Spain to find his long-lost mother.
