Tian ZhongXingxiong (played by Nishikawa Daisuke) is an ordinary 14-year-old middle school student. If he hadn't met that time, he might have been submerged in the crowd all his life, leaving no trace. The arrangement of fate made him meet Nan Longjie (played by Ueno Yuma), a returnee youth two years older than himself. Longjie has a flamboyant personality and a stubborn love for music. In New York, he once formed a rock band. The colorful life and overly persistent personality made him part ways with the band. However, Longjie finally found the rapper Chiba Hengmei (played by Ohata Shintaro) and the 18-year-old bassist Ping Yixing (played by Nojima Kenji), determined to form another band to pursue his dream. With Xiaoxiong and the transfer student Yingjing Yuzhi (played by Nara Tetsu), who is good at drums, the double lead singer band named BECK was officially formed. The boys who love rock and roll run happily towards the other side of their hearts. This film is adapted from the original manga of the same name by Haroldo Zuoshi.
