A reclusive artist, Sarah, discovers an old, forgotten music box in a dusty antique shop. When she winds it up, a haunting melody fills the room, and a shadowy figure emerges from the box, whispering promises of artistic fulfillment. As Sarah becomes increasingly obsessed with the music box and its mysterious powers, she realizes the figure is not a muse but a malevolent spirit feeding on her creative energy. The more she relies on its influence, the more her art becomes twisted and dark, reflecting the figure's sinister intentions. Sarah must choose between sacrificing her soul for artistic success or confronting the malevolent spirit and reclaiming her own creativity.
