Someone is performing a bastardized version of the Black Mass in San Antonio, Texas where Catholic Nuns are sadistically tortured, and slain. A scrupulous attorney hires an elite private investigator, Frank McLaughlin, to investigate on behalf of an anonymous client. Frank elicits the help of a White Witch, Fiona and they quickly fall in love. Time and time again, Frank's resolve is tested as he is torn between logic, duty and his own undefined faith. The police are baffled as the Catholic Archbishop cries out for action while silently pointing an accusing finger at the World Church of Satan. Chief of Homicide, Norman Lenowski, has pulled out all stops to solve the murders by creating a special task force called "Operation Madness." Fearing a cataclysmic showdown with the Catholic hierarchy, the World Church of Satan, headed by Lord Nicholas Stonefire, launches its own investigation into the serial murders. The Catholic Papacy unleashes their ultimate troubleshooter, an Assassini. The carnage continues while all efforts cross and collide until the shocking end. There is ample fodder here for all conspiracy theorists.
