The greedy businessman and the mayor of the town want to turn the site of the shrines into a money making scheme replete with spa hotels and theme parks. Our school girl hero Mikayo and her class mates must use all their courage and resourcefulness to defeat the samurai zombies. With the help of Mikayo's mobile phone and the local barber turned shrine tender they battle the zombies and restore order to the town.
