Fascinated by everything he sees, Jack decides that this year Halloween will take an unexpected turn: he will be the one to bring Christmas to his town! Convinced that he can create his own version of the holiday, he starts planning it in his style, using spooky touches and characters from horror tales.

Meanwhile, his platonic love for the sweet rag doll Sally, who has her own premonitory visions, adds to the mix. As Jack delves into his nightmarish world, he must face the reality that every holiday has its own spirit and that some things, no matter how tempting, should not be mixed. The movie is a stunning visual journey filled with unforgettable musical numbers and a strong message about identity and acceptance.
