Cast out of heaven after angering God, Lucifer descends to hell. As she makes her plunge, she comes upon a beautiful young woman at just the right moment. Young, naïve, and perfectly pure, Maria seeks to help the fallen angel but winds up taking in more than she bargained for. Now, with her heart plucked from her chest and her body filled up with Lucifer's angelic blood, she's become the perfect tool in the fallen angel's mission to take over hell. With hands and mouth all over the whimpering maiden, and the eager-to-please sin of Envy at her beck and call, Lucifer will take the crown of hell-and whatever else she desires. But is her drive and fury enough to face the Mortal Sins that rule the underworld or will she fall prey to their demonic yearnings?
