Couldn't find anything else to do on Halloween night, on account of him being too old to go trick-or-treating, Rota (T. Rozier) decides to head to the mall to find something to entertain himself. But little does he realize that all of this will have to wait, because both Mars and Moon have aligned and an invasion of Harukos have risen from the depths of the Earth to locate the lone prey in the mall and Rota must do anything he can to escape the Haruko-ridden mall of the damned.
