Three hundred years ago, accused witch Hester Warren buried a magical box in Mystic Notch. The secret contents within have the power to bring disaster to the town and when the box is dug up at a groundbreaking ceremony for the new Mystic Notch Historical Museum, Hester's ghost and that of her cat make an appearance to warn the humans and enlist their help to ensure the box doesn't fall into the wrong hands. Too bad the only one listening is Pandora, the cat.
