Father Steve, a priest highly-upheld amongst the Church, is given the important task of transcribing ancient texts for the Vatican library. One of the books takes a hold of Steve’s attention, as if it calls to him. Steve reads the book. His body begins to decay and corrupt the more he reads, falling into the dark powers sealed within the book itself.

One of the parish’s nuns, Kyoko, approaches Father Steve during his transcription, only to react in horror to the man’s corruption. She runs to her fellow sister, Karina, and warns her of his actions. Karina attempts to exile Father Steve but it’s too late. The devil himself channels through the man’s body, giving him the power to freeze both Karina and Kyoko in place.

Thrusting his sinful urges into the two women, Steve uses their bodies with no resistance, slowly corrupting the two nuns to join him in submission to the book’s power.
