Nao Shingaki has a part-time job at a mini-mart. Outwardly it looks like any other store, but there is something unmistakably abnormal about the place. Inside the air is choked with vengeful spirits. Outside the backyard reeks of a horrible smell. The owner seems to be overjoyed by the severe injuries sustained by a sales rep for a major franchise, while his wife suffers from an unknown madness and spends all of her time staring into the security cameras. Now the spirits have claimed the souls of the night-shift clerk and several customers. Nao faces the task of somehow trying to escape this demonic terror!
