Ryo works as a window washer for high-rise buildings in Tokyo, spending his days suspended in the air on a gondola by himself. Inside one of these apartments, 11-year-old Kagari lives with her neglecting mother and plays with her two pet birds. One day, Kagari finds one of the birds injured and Ryo, who happens to be washing her window outside, takes her to the veterinary hospital, ushering in an unlikely friendship and journey of self-discovery.
