When Melissa’s daughter is dying of cancer and the doctors seem helpless to stop it, she and her husband make a deal with the devil to save their daughter.
But they misunderstand the terms of the deal, and Melissa is shocked when the devil comes to collect. Once Lucifer explains that she will conceive, bear, and raise his child, Melissa becomes hesitant. But there is no way to turn back without sacrificing her daughter’s nearly miraculous recovery, so she invites the devil into her bed.
In the bedroom, Lucifer sheds his human facade and takes on his true form – a hulking beast with blood-red skin and thick, black fur, every part of him much larger than any man Melissa has ever seen. Her apprehension grows when he crawls into bed beside her, until she discovers that the Prince of Darkness is a master of everything sinful and pleasurable.
