Here is the official synopsis of the film from laika.com:
A misunderstood boy who can speak with the dead takes on ghosts, zombies and, worst of all, grown-ups, in order to save his town from a centuries-old curse.
Norman Babcock is an outcast in his small New England town. When a horde of zombies is unleashed on the populace, Norman learns he must use his paranormal powers to make things right again. That’s not an easy task when you’re only eleven. And you’ve just been grounded.
