Tazuru is a college student working the night shift alone in a convenience store. The manager of the store, who has been missing for days, is found dead in the basement, with his eyes gouged out. Tazuru tells the police the creepy events that unfolded on the four previous nights: getting sent mysterious SD cards with disturbing videos on them, the door chime ringing with no reason, weird things on security camera, being visited by a weird old lady looking for her grandson, and a creepy ghost boy. Inspector Sawatari is initially incredulous, but then similar events start happening to him too.
