When fifteen-year-old actress Lucy Carter loses her older sister in a car accident, her mother shuts down and her father can't hold the family together. Their only choice is to ship Lucy off to the Edmond School for Performing Arts. But boarding school is no cure for Lucy's grief. With failing grades, wooden stage performances, and curfew violations, Lucy is threatened with expulsion. For the once talented Lucy, it feels as though she has nowhere to turn.
One night, Lucy hears mysterious music drifting through the school's old heating system. The music leads her to a troubled but passionate songwriter whose brilliance gives her the strength to perform like never before. Yet their intense relationship puts Lucy in a precarious position: if she follows her muse, will she lose herself? And if she breaks it off, can she stand on her own again?
