On a hot summer day, the sound of cicadas can be heard. Tarao has just moved into an apartment building, and in the elevator he encounters Shuri, a beautiful married woman who lives next door, and the elevator comes to a sudden halt. The two are covered in sweat, but they can't get through on their cell phones, and when they press the emergency button there is no response, so they are trapped inside. Dehydrated and in a daze, Tarao begs Mitani to let him drink her sweat, hoping to quench his thirst.
