A group of schoolgirls have formed a band to perform at their high school cultural festival (Japan) in three days' time, but the guitarist and singer have quit. The remaining members, Kei, Kyoko, and Nozomi, decide to perform covers of Blue Hearts songs, including "Linda Linda", but need a new singer. They ask the first girl that walks by, Son, a Korean exchange student who is not fluent in Japanese, and name their band Paranmaum. The first day ends with all the girls working their hardest to learn their parts. Son practices at a karaoke parlor, and Kyoko talks to her crush, Kazuya.
