Every night, Jay drives his cab around Tokyo, harboring a slightly crazy hope that he'll see his estranged daughter, Lily, one day. With his hopes faded, Jay resigns himself to the idea of finally returning to France.

But when his cab company asks him to take charge of a special fare, a girl aged twelve with pale blue eyes gets into his car. While he's convinced it's her, she doesn't recognize him. As the days go by, a relationship develops, a chauffeur-client one. But can this relationship ever become a father-daughter one again?
