Only three days before their high school festival, guitarist Kei, drummer Kyoko, and bassist Nozomi are forced to recruit a new lead vocalist for their band. They choose Korean exchange student Son, though her comprehension of Japanese is a bit rough! It's a race against time as the group struggles to learn three songs for the festival's rock concert—including a classic '80s song by the Japanese punk rock band The Blue Hearts called "Linda Linda".
