In the second hour of NBC's event series "Revelations", astrophysicist Dr. Richard Massey (Bill Pullman) and Sister Josepha (Natascha McElhone) are led deeper into a whirlwind of events that may signal the End of Days. With Satanist Isaiah Haden (Michael Massee) safely in prison, Dr. Massey attempts to return to his old life, only to be pulled out of it once more when he is asked to reconsider the possible source of messages that are transmitted by a young girl languishing in a coma that could be coming from his slain daughter, Lucy. Massey reluctantly agrees to meet with Eklind (Jesper Christensen), the man who is funding Sister Josepha's research, and together, Massey and Sister Jo embark on their investigation that begins with questioning the origin of a "miracle child"--a sole survivor of a shipwreck off Patmos, Greece.

Dr. Richard Massey (Bill Pullman) and Sister Jo (Natascha McElhone) travel to Italy to speak with the mother of the miracle child who believes that shadowy figures attempted to take the baby from her. In the meantime, a mysterious seductress leads Massey's stepson Hawk (Mark Rendall) away from the protection of his bodyguard and into the grasp of Satanists, Ogden (guest star Fred Durst, "Limp Bizkit") and Tulia (Caryn Green). And, imprisoned Satanist Isaiah Haden (Michael Massee) attempts to track down Olivia (Chelsey and Brittney Coyle), the young girl languishing in a comatose state.

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.
