Jack Skellington is the beloved Pumpkin King of Halloween Town, but he has grown tired of leading the usual scares every year. Then he stumbles upon a mysterious tree-shaped door deep in the Hinterlands and falls straight into Christmas Town--an enchanting place like no other, full of sparkling snow, merry elves, and twinkling lights. Reinvigorated, Jack returns to Halloween Town and recruits the citizens into his new plan: to organize Christmas themselves! But even with aid from his loyal dog Zero and the resourceful rag doll Sally, challenges lurk around every corner. Sally sees a terrible vision of Jack falling into danger, and the mysterious Oogie Boogie hides in the shadows. Will Jack's dream of creating the perfect Christmas come true... or is it destined to become an utter nightmare?
