Dr. Richard Massey's (Bill Pullman) kidnapped stepson, Hawk (Mark Rendall), is presented with a horrible choice by his Satanic kidnappers Tulia (Caryn Green) and Ogden (Fred Durst): either he or his mother's unborn child will die. Meanwhile, Satanist Isaiah Haden's (Michael Massee) trial begins, and his charisma and rhetoric gain him increasing respect from his fellow prisoners. In London, Massey and Sister Jo (Natascha McElhone) meet with an expert on Satanism, and hope that he will be able to help them find Hawk and foil Haden's plans. Sister Jo's order, the Sisters of Mercy, ask Massey's assistant Rubio (Martin Starr) for help, as they fear that their convent has been infiltrated by Haden's men.
