Haunted by the recent loss of his mother, a man seeks solace in the familiar objects of his childhood home. He finds a peculiar, heirloom music box that has always unnerved him with its discordant tune and chipped porcelain ballerina. But as a storm rages outside, a strange compulsion leads him to wind the box, unleashing a terrifying supernatural presence. The box begins to play a new melody—a familiar nursery rhyme sung in his mother's voice. As his reflection in a nearby window takes on a life of its own, he realizes the box isn't just playing a song; it's luring him into a horrifying union. Trapped by the object he once hated, he becomes a new player in a chilling waltz of possession and dread, his own will and voice consumed by the music box’s malevolent tune.
