The Vatican tapes plot revolves around an intense struggle for power between two opposing forces: light (God) and darkness (Satan). The story centers around Angela Holmes, who appears to be like any other 27-year-old woman until she suddenly begins experiencing inexplicable occurrences that have far-reaching consequences.

As the main character navigates her new reality, it becomes clear that a malevolent entity has taken possession of her body. This demonic presence is capable of causing significant harm and destruction wherever Angela goes, leaving behind a trail of chaos in its wake.

In an attempt to understand this phenomenon and possibly stop the impending doom, Father Brennan asks for help from two renowned exorcists: Father Ben Hall (a seasoned priest with extensive experience dealing with possession cases) or Father Matthew. Together they embark on a perilous journey into the heartland of Rome's most sacred institution - The Vatican itself!

Throughout their quest to free Angela from this malevolent force, both sides engage in an all-out battle for her soul; between good seeking redemption through faith & love versus evil tempting eternal damnation through fear and despair.
