A story of love and frailty, Air Doll takes the essence of what it means to be human and distills it down to its purest form in this bittersweet love story that smoothly intertwines fantasy and reality.
In a shabby, rundown apartment in an old part of Tokyo, a bright beacon of purity shines into being one day. Silent and motionless, the air doll that belongs to quiet and retiring middle-aged Hideo (Itsuji Itao) has never been anything out of the ordinary. Each evening after work, he chats with her over the dinner table, bathes her and makes love to her before turning in for the night. However, after he leaves the house one day, the air doll begins to twitch and move, miraculously coming to life.
Like a newborn marvelling at the wonder of the world, she is awestruck at the beauty of everything around her. Tottering about in her tiny maid's uniform, she ventures outside the apartment with childlike curiosity. As she wanders through the city, the air doll is enthralled, talking to anyone she finds and trying to comprehend her own ephemeral existence. Though her life is only a few hours old, it changes forever when she walks into a video store and falls helplessly in love with the clerk, Junichi (Arata).
