シェイクハンズ (2013)

Four middle school students, Kota, Daichi, Naoki, and Kento, haven't found their place at home or school, so they gather in a vacant lot by the sea absorbed in their favorite music and dance. It's the place where they can be their honest selves. Unfortunately, their friendship dissolves trivially. It has the potential to be revived as they honor their promise to one another when they participate in dance competitions.
