A man is being haunted by a ghost, since exorcisms did not work they want Moore to solve the case. The clue is a card that says the fifth ghost will kill them unless they repent their sins. Since the time that card was sent, the master installed a door that needs a pin code and fingerprint scan to access the top floor. The master, lady, and the installer of the door are friends who are hiding a secret about the sin. All the accidents happen on Butsumetsu day, the day Buddha dies and the unluckiest day on Earth. On that day the installer was found hanged on the balcony of the third floor. The master was not home so the door could not have been opened.
