‘Twas a long time ago, Longer now than it seems in a place that perhaps you've seen in your dreams For the story that you are about to be told began with the holiday worlds of old Now, you've probably wondered where holidays come from. If you haven't I'd say it's time you begun. For the holidays are the result of much fuss and hard work from the worlds that create them us Well you see now, quite simply that's all that they do, making one unique holiday especially for you But once, a calamity ever so great occured when two holidays met by mistake Halloween Town is a dream world filled with dark creatures such as deformed monsters, ghosts, ghouls, goblins, vampires, werewolves and witches. The Pumpkin King, named Jack Skellington, leads them in a frightful celebration every Halloween, but he has grown tired of the same routine year after year. Wandering in the forest outside the town center with his ghost dog, Zero, he finds a cluster of trees each with a door which represents a certain annual holiday. Jack is drawn to the tree with the Christmas tree-shaped door and opens it which leads to a portal to "Christmas Town". Impressed by the feeling and forbidden of Christmas, Jack presents his findings of the holiday to the Halloween Town residents. They fail to grasp his meaning and compare everything he says to their idea of Halloween. Jack undertakes several experiments to try to understand Christmas logically, but he becomes frustrated when he fails to understand. However, he realizes that just because he can't understand Christmas does not mean he still can't enjoy it; so he announces to Halloween Town that this year they will take over Christmas, and that he will usurp the role of Santa Claus, known to him as "Sandy Claws". Sally, a rag doll woman who was created by the town's mad scientist and has romantic feelings for Jack, has a premonition of Jack's Christmas ending badly. When she tries to warn Jack of the imminent disaster, he misinterprets her anxiety to mean that she is worried when given the responsibility to make Jack's Santa costume. Meanwhile, Jack assigns Lock, Shock and Barrel, a trio of mischievous children, to bring Santa to Halloween Town. When he arrives after being kidnapped, Jack tells him of his plan that he will take over Christmas this year, much to Santa's protests. After this and against Jack's instructions, and largely for their amusement, the trio deliver Santa to Oogie Boogie, a gambling-addict bogeyman who plots to play a game with Santa's life at stake. Christmas Eve arrives and Jack prepares to embark into the sky on a coffin-like sleigh pulled by skeletal reindeer. Sally tries to stop him by releasing fog juice, but Jack is inspired by Zero's glowing nose and orders the ghost dog to lead the team. He begins to deliver presents to children around the world, but the gifts (shrunken heads, Christmas tree-eating snakes, etc.) only terrify the recipients. Jack is believed to be an impostor attempting to impersonate Santa. The army is alerted, and, using searchlights to spot him, they open fire on him with artillery. Jack believes at first that the shells are merely fireworks, set off to thank him; by the time he realizes the truth, it is too late. The sleigh is shot down and Jack is presumed dead by Halloween Town's citizens, but in fact he has survived the crash, landing in a cemetery, where Zero is seen finishing up reassembling Jack. Although he is depressed by the failure of his plan and the damage it caused, he realizes that his Christmas adventure has helped him to rediscover his love for scaring people. Having come up with new ideas for next Halloween and wanting to "set things right", he rushes back to Halloween Town by going through a tomb. Meanwhile, Sally attempts to free Santa by distracting Oogie, but fails and is also captured by Oogie. Sally claims Jack will free them, but they hear the Mayor saying Jack is dead. Jack slips into the Oogie's lair and frees both Santa and Sally just before Oogie can drop them into a fire pit. Jack then confronts Oogie, who sets off several lethal traps, which Jack nimbly avoids. Oogie tries to escape, but Jack uses a single loose thread hanging from the bogeyman's sewn rag structure to rip him open, exposing the bugs that he is made of. He falls apart, and most of his bugs fall into the fire pit. The last one is squashed by Santa, who then reprimands Jack before setting off to deliver his presents to the children of the world. Jack asks Sally how she got into Oogie's lair in the first place and he realises that she was trying to help him because she has very strong feelings for him. When Jack and Sally return to Halloween Town, the citizens rejoice that Jack is alive. Moments later, Santa is seen in the sky, making snow fall over Halloween Town to show that there are no hard feelings between himself and Jack. The townspeople are confused by the snow at first, but soon begin to play happily in it. Jack follows Sally out into the graveyard after seeing the Doctor with his new creation. Jack and Sally sing a romantic song together where Jack unmasks his deep love for Sally and she returns these feelings for him. They then embrace their new future together and share a very passionate kiss on top of the spiral hill in the graveyard. Zero watches them from afar before flying into the night sky forming a bright star shape and ending the film.
