The lights dim at Seoul's biggest concert venue as five members of the rising KPop group Celestial take the stage. Lead vocalist Min-jun notices something wrong in the crowd. Dark shapes move between the screaming fans, and people begin collapsing. The performance becomes a battleground when demons emerge from the shadows, drawn by the music's power. Min-jun discovers his voice can banish the creatures, but using this ability threatens to destroy his vocal cords and end his career. His bandmates each possess their own supernatural gifts, but they must choose between their dreams of stardom and protecting innocent fans. As more demons appear at venues across the city, the group realizes the attacks are coordinated. Someone is using KPop concerts as hunting grounds. Min-jun and his teammates go underground, performing secret shows to lure out their enemies while searching for the source of the demonic invasion. They face an impossible choice between the spotlight they've worked their entire lives to reach and a hidden war that could cost them everything they love.
