Canadian soprano Renata Bruno is tired of waiting for her big break. Unfortunately, her boss, the conductor of a chamber ensemble, sees her as little more than background material. When she learns of an opportunity to sing solo with a different troupe in England, she knows she must seize it. Especially when she hears the group is to perform Mozart's Requiem, her favorite work. As soon as Renata decides to make her move, a strange, sultry presence invades her life. She begins dreaming of a man, one who makes love to her, bewitching her. It isn't long before her night lover leaves startling proof of his nocturnal presence, making her doubt her senses. To compound her discomfort, she learns her new conductor is the college boyfriend who broke her heart years ago. As Renata grapples with old hurts and renewed passion, she must also fend off the increasingly fervent advances of her night-time visitor. She realizes she is under the influence of an incubus, a sexual demon. It becomes harder to resist the incubus when she learns he has a name and had a tragic history. The more she discovers about his past, the more she realizes they are linked in more ways than one. Renata begins to rediscover love and her sense of faith, but will it be enough to save her night lover from an evil curse? And will it destroy her in the process?
