A fortune teller in the demon world, called an interpreter of signs, reads the fortune of a paranoid demon named Christopher, and discovers he's not telling her the full story. After forcing him to reveal he's found a device, a chronolet, that allows its user to travel back in time, the interpreter pleads with Christopher not to use the device. Not only is it impossible for her to read the fortune of a past which hasn't happened yet, the device poses too great a danger. Will he take her advice or will he risk our future and his own for a demon's chance at an untold fortune?
