A life-size air doll (Doona Bae) is kept in the retro apartment of Hideo (Itsuji Itao), but over time she develops a soul of her own. One day she cheerfully fixes up her outfit and decides to enjoy a walk outside alone. She eventually meets a video store clerk named Junichi (Arata) and secretly falls in love. She hatches a plan to get a part-time job in the store alongside him, but an unexpected turn of events throws her fragile existence into turmoil. Through her subsequent journey of self-discovery she explores what it really means to be human.
