A lively children's tale follows a neighborhood club that grows when the youngsters admit a much younger boy, then accompanies family voyages that carry them from California to New York and across the Atlantic. Episodes blend everyday play and club rituals with travel scenes and foreign sightseeing, including encounters in France, a mysterious lost bag, and the alarm of a missing member that prompts searching and quick thinking. Through mishaps, discoveries, and cooperative problem solving the children strengthen friendships, broaden their horizons, and end the narrative reunited and in high spirits.
