When the music starts, the nightmare begins.
Charlie Walker vanishes from his bedroom without a trace, leaving his parents, Jim and Lara, drowning in grief and desperation. As Detective Graves and Reese chase a trail of missing children, they uncover a chilling pattern—scrawled musical notes spiraling across a madman's walls, whispering of monsters that steal the innocent. Jim's search leads him to a portal beneath Charlie's bed, a gateway to a grotesque realm ruled by Leviathan—a sadistic entity who offers a cruel bargain: one soul saved, another damned.
When Graves faces the music, Reese is left to pick up the bloody pieces as she teeters on the edge, haunted by visions of suffering. In the end, the survivors must face an impossible choice: silence the horror or let it consume them all. In a world where faith fractures and courage flays, one question remains: who will pay the price to end the song?
