The story follows an aviator who meets a little prince from an asteroid. The prince tells the aviator about the other planets he visited, each inhabited by different eccentric individuals - a king, vain man, drunkard, businessman, lamplighter, and geographer. During his travels, the little prince falls in love with a flower on his asteroid and is confused by these feelings. He eventually arrives on Earth where he befriends a fox who teaches him about life before returning to the aviator, though it is implied the little prince may soon die.
