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.
