The midnight hour approaches in an almost empty all-night diner. Mari sips her coffee and glances up from a book as a young man, a musician, intrudes on her solitude. Both have missed the last train home.

Later, Mari is interrupted again by a girl from the Alphaville Hotel; a Chinese prostitute has been hurt by a client, and she needs Mari's help.

Meanwhile Mari's beautiful sister Eri sleeps a deep, heavy sleep that is 'too perfect, too pure' to be normal; she has lain asleep for two months. But tonight as the digital clock displays 00:00, a hint of life flickers across the TV screen, though the television's plug has been pulled out.

Strange nocturnal happenings, or a trick of the night?
