It's Halloween in South Park again, and all is not well. Father Maxi denounces the holiday as evil, and expresses his disgust in inviting the band Korn to perform, which could only compound the evil that day. Korn and the rest of South Park start seeing pirate ghosts (or are they ghost pirates?) around the pier, making the concert a distinct impossibility. With the help of their space chicken friend, Niblet, Korn set's out to foil the ghosts evil scheme.
