A lonely middle-aged woman named Bongja works in a small restaurant where it is her job to prepare maki rolls, a kind of sushi. She leads the life of an old maid and one of her small pleasures is indulging in a somewhat immoderate amount of saké. Because of recurrent problems with drinking Bongja eventually loses her job. Desperate and depressed, she returns home where to her surprise she finds a strange girl asleep in her house. This mysterious person who, without any explanation whatsoever settles into Bongja’s place, slowly begins to fundamentally change not only the life of her amazed and somewhat startled hostess but even her neighbours as well. Gradually they all drop the masks behind which, their whole lives, they have hidden their desires, and begin to give vent to previously suppressed feelings and secret aspirations, whether of a sexual, violent or even deadly nature. . . .
