After five years at the same company, office worker Retsuko navigates a workplace filled with daily irritations. She arrives at work in her sandals and encounters colleagues who either flatter the boss or ignore their duties. Her boss, Ton, assigns her menial tasks such as dusting his desk and fetching tea, then burdens her with a large stack of papers that keeps her working late into the night. To cope with these frustrations, she visits a karaoke bar where she sings death metal. This routine highlights the contrast between her stressful professional life and her private outlet for stress relief.
