"Guns" was a punk band that became a social phenomenon in the 1980s. At the height of their popularity, one of the member Hal caused an injury and the band was suspended. Thirty years later, the band starts to reunite under the leadership of Ichi, motivated by the pathetic and impure motives of their leader, Animal. However, when they begin rehearsals, the discrepancies in their thinking and growth as a band become apparent.
