A hot summer day when you can hear the cicadas. Tarao, who has just moved into an apartment, runs into Akari, a beautiful married woman who lives next door, in the elevator, and the elevator suddenly stops. The two of them, drenched in sweat, can't get through when they call on their cell phones, and when they press the emergency button, there's no answer, so they're trapped. While feeling hazy due to dehydration, Tarao begs Mitani to let him drink some of her sweat so that he can moisturize himself with it.
