After five years at the same company, office worker Retsuko has to deal with many daily annoyances. She inadvertently arrives at work in her sandals, interacts with co-workers who either kiss up to the boss or couldn't care less about work. Her boss, Ton, makes her do menial tasks like dusting his desk and getting him tea, and then piles a bunch of papers on her, keeping her late at night. Afterwards, she lets out her frustrations by going to a karaoke bar and singing death metal. (Source: Wikipedia)
