As the new school year begins, Tomoko buys a saxophone and discovers Takuo playing his keyboard. The members of the swing band gather at school and decide to buy their own instruments. The girls get supermarket jobs to earn money, but Tomoko and several others lose their wages when a cooking demonstration gets out of hand, triggering the store's fire sprinkler system. The remaining girls spend a day picking matsutake mushrooms, but are attacked by a boar; they kill it and claim reward money, as the boar had been destroying crops. With the money, the girls buy cheap damaged instruments, and the two rockers convince their ex-boyfriends, who operate a wrecking yard, to repair them.
