Art Atchinson Aimesworth, inventor, adventurer, and crime-fighter, receives a summons from Santa Claus himself. But why did Santa call? Art, his little sister Esther, and his best friend Spauldiing, journey North in their Yuletide Flyer. They meet Mr. and Mrs. Claus and engage in an exciting battle with the Dark Elves before returning home. The next day, they receive gifts from Santa: a canoe for Spaulding, a puppy for Art, and two letters for Esther. The contents of the letters reveal the real reason why Santa called.
