The Air-Conditioning System

Storyline: The Air-Conditioning System (1997) introduces us to a young man in his flat, and the ways of communication with his girlfriend. The sky is blue and skirts are put on the balcony for drying. The wind will carry everything away, just like the noise and music or the porn we watch with him later on TV (he prefers to look at western blonde women). What will happen when the young woman in her flat will have found out soon that he is looking at her (and listening to her) via the air-conditioning system?
