This story revolves around a young boy named Wolff, living with his cold-hearted and miserly aunt in a European city. Despite his aunt's lack of affection and the harsh treatment he faces at school, Wolff maintains a kind-hearted and hopeful demeanor. During a chilly Christmas Eve, as Wolff and his schoolmates return from midnight mass, he shows compassion towards a sleeping, barefoot child in church by leaving one of his wooden shoes for him. The aunt, in her cruelty, mocks him, expecting nothing but a harsh lesson for his generosity. However, the next morning reveals a miracle: the very shoe Wolff gave away is filled with toys and sweets, while the wealthier children's shoes only contain switches. This twist of fate—catalyzed by the revelation that the barefoot child was Jesus—highlights the moral of selflessness and love being rewarded, showing that true wealth comes from a generous heart.
