Kei Omori is a caregiver who has left his previous job at a small-scale care service to come work at a large-scale nursing home. But he is unable to hide his tremendous discomfort with a management style that prioritizes efficiency and risk control in the name of accommodating large numbers of residents. It is under these circumstances that Mieko, an elderly woman living with dementia, moves into the nursing home.

When Kyoichiro comes home, he hears that his 14-year-old son Kyosuke was stabbed to death. The person who killed Kyosuke turns out to be 13-year-old Mitsuru. The two boys were classmates. Due to Japan's juvenile law, Mitsuru will not receive commensurate punishment for his crime. Kyoichiro points his anger at Mitsuru and his mother Hatsumi, but Kyoichiro sees that Hatsumi also suffers from her son's actions.
