Ten-year-old Akira (Yusaku Suzuki) and Koichi (Shingo Mizuno) are best friends from school in a Tokyo suburb. In the second half of the year, they change classes and slowly their relationship changes. Akira meets Shuna (Yuya Suzuki), a lonely boy who is a crafty maker of plastic models. Koichi becomes closer with the problematic Samajimo who is a petty thief. This is an intimate film by Akihiko Shiote about an unsentimental friendship and growing up. Influences by Susumu Hani and Francoisa Truffaut are evident.
