Jack and Sally are finally together and nothing seems to be keeping them apart. Or does it? Sally suddenly realizes how heavy the crown she's now wearing is and is afraid she's not good enough to be Pumpkin Queen. Jack tries to comfort her, but he's been the king of Halloween town for a long time and knows how things work. One dark night, as Sally tries to get a break from her great responsibility, she unleashes something... Ancient? Something evil, even?
