In a bustling workshop at the North Pole, a little human named Buddy lives a joyful and carefree life among elves. However, one day he discovers that he is different from the others: he is human, not an elf. This revelation leads him to embark on an epic journey to New York City, where he tries to find his real father, Walter Hobbs, a businessman who has no idea of his existence.
Buddy arrives in a city that has nothing to do with the Christmas magic he knows. His overflowing enthusiasm and innocent view of the world hilariously clash with the harsh urban reality. Despite being looked at with strange eyes, Buddy strives to adapt, seeking to share his Christmas joy with everyone. From decorating a giant Christmas tree to singing carols in the middle of Central Park, his actions provoke laughter and heartwarming moments.
As the story unfolds, Buddy faces challenges ranging from his relationship with his father, who initially rejects him, to restoring the Christmas spirit in a city that seems to have forgotten it. With the help of a kind yet skeptical woman named Jovie, Buddy attempts to show that love, family, and the magical spirit of Christmas can change everyone’s life, even in a place where joy seems to have disappeared. In the end, his overflowing optimism and unwavering faith in Christmas become the catalyst to mend his father's heart and the city.
