The story follows two siblings who build a makeshift flying machine and are carried into an enchanted realm. Their episodic adventures bring them into contact with eccentric inhabitants, talking animals, magical objects (boxing gloves, a magic umbrella, a whistle), a mysterious stranger, and a young woman who recounts a strange history. Gran’ma and Gran’pa pursue the children and take part in comic rescues, while dancing masters, invisible people, and a rubberlike river create further obstacles and amusements. The narrative culminates with palace and magician episodes before the family is reunited and returns home. The tone is whimsical, childlike, and imagines practical ingenuity mingled with gentle fantasy.
