The film uses flashbacks to tell the story of Belle's first Christmas as a prisoner in the castle. Belle awakens the castle's long-lost joy, allowing the castle to enjoy the warmth of Christmas again, and finally allows the beast to experience the bright side of life again and abandon his selfish and independent mentality. Only then do Belle and the beast know each other. In addition to the original cast of the film, this film also has three new characters, including a Christmas tree ornament doll named Angel, the insidious organ, and his little follower Piccolo. Belle must overcome the organ's evil deeds in order to fulfill her wish and let the beast enjoy the joy of Christmas again.
