It's their last annual high school festival, and classmates Nozumi (Shiori Sekine) and Kyoto (Aki Maeda) decide to put together a rock band to play "Linda Linda Linda," a hit punk song in Japan. But their singer and guitarist quit, so they get a Korean girl (who can barely speak Japanese) to sing and a guitarist who usually plays keyboards. They have two days to learn to play together and win the school festival before graduation comes and they must enter the real world.
