The novelist Sawai enjoyed seeing the mirage on the Kugenuma Coast with his wife and friends as a breather for work. However, the headache of the having a disease occurred frequently as usual, and various illusions and hallucinations which seemed to invade from the mischief of the sand of the coast or the crack of daily life were seen, and an ominous event was encountered.

At the bar, three office workers enjoyed drinking alcohol and discussing their views on life. Eventually, Sawai, who got drunk, began to talk about the daily events he spent with a strange woman he met in the graveyard a few months ago.
