Louise has no reason left to stay in the city. She can't see her son, Joseph, who is away at boarding school, where he performs in a prestigious boys' choir. Her troublesome neighbor has begun blasting choral music at all hours of the night - and to make matters worse, she's the only one who can hear it. Hoping to find some peace, Louise convinces her husband to buy a country house in an idyllic community called Swallowfield. But it seems that the haunting melodies have followed her there. Growing desperate, she begins to worry about her mental health. Against the pleas and growing disquiet of her husband, Louise starts to suspect that this sinister choir is not only real but a warning.
