Dynamic Chord is a record label and music agency representing the hottest artists right now, including four of the country's most popular bands. They are rêve parfait, with its own unique worldview and progressive sound; Liar-S, an emo rock band; KYOSO, a group of highly polished performers; and apple-polisher, which fuses dance with rock and roll. Against the backdrop of Japan's four seasons, this realistically depicted documentary movie follows the encounters, breakups, and trajectory of these 16 band members as they vie for musical preeminence.
