Vocalist Gi Seok, who was kicked out of the band two years ago, suddenly receives a call from bassist Myeong O asking him to join them on stage, and they arrive backstage. However, just before the performance, a conflict erupts between Gi Seok and guitarist Yu Won, who hadn't noticed Gi Seok's arrival. This sparks a resurgence of past wounds that led to his departure from the band. To make matters worse, Gi Seok finds himself embroiled in a fight with another band.
