Hour One

From executive producer Gavin Polone (""Panic Room"") and writer/creator David Seltzer (""The Omen"") comes ""Revelations,"" a six-hour event series starring Bill Pullman (""Independence Day"") as Harvard professor Dr. Richard Massey, an astrophysicist who is certain that all worldly events can be explained by Science. In the series premiere, Dr. Massey is dealing with the tragic murder of his 12-year-old daughter by a maniacal murderer, Isaiah Haden (Michael Massee, ""24""), who was captured and imprisoned. After a strange course of events, Massey is challenged by a nun, Sister Josepha Montafiore (Natascha McElhone, ""Solaris""), who leads him on a journey through the unfamiliar world of faith. Drawn together by personal tragedy, these unlikely partners -- one who worships God and one who worships Science -- are propelled into a deepening mystery, finding evidence that the world, as predicted by The Book of Revelation, has reached The End of Days.

Hour Two

In the second hour of NBCÓs 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.

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.
