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. The musician has plans to
rehearse with his jazz band all night, Mari is equally unconcerned and content
to read, smoke and drink coffee until dawn. They realise they've been acquainted
through Eri, Mari's beautiful sister. The musician soon leaves with a promise to
return before dawn. Shortly afterwards Mari will be interrupted a second time by
a girl from the Alphaville Hotel
