While caring for her father-in-law at home, Momose earns certification as a home-care worker. Realizing he will eventually need medical assistance as well, she takes a part-time position at the nearby Komiyama Care Service to pursue a more advanced qualification. She does not know that the manager, Koyama, is notorious throughout the company for sexual harassment. He singles Momose out as his next target and subjects her to escalating abuse under the pretense of hands-on caregiving lessons.
