Céline, 11, meets Peter, 40. Together they go on a "luminous journey" in his beautiful red truck. She, escaping her desperate and incestuous father; he, far from his native Scotland and the sad memory of his lost wife and daughter. In the course of a few days, a few words, Céline experiences her first true moments of childhood and lightness, exhilaration and trust. Peter goes towards the last days of a life that he offers, like a sublime and aging angel, to this wounded child.
