The Prince's Voyage (Le Voyage Du Prince)

Tom, a simian boy, discovers a simian adult on a beach. He takes him to his home, situated in an old museum, where the older man claims to be Prince Laurent from across the ocean. But in Tom’s world, overseas visitors are little more than the subject of legends. The Prince and the boy become friends and, much to the dismay of Tom’s guardians, they decide to explore the unusual world, where strangers are not welcome.
