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.

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'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.

Dr. Richard Massey (Bill Pullman) and Sister Jo (Natascha McElhone) travel to Prague to speak with a noted expert on Satanism, who leads them to a secret library hidden in a crypt. Within the crypt, Massey and Sister Jo find a strange box that contains a puzzle that may unlock clues about the birth of the Anti-Christ. Back at the Sisters of Mercy convent, the sisters and comatose Olivia find themselves under attack by followers of Satanist Isaiah Haden (Michael Massee). Meanwhile, Haden attempts to escape from prison, and Hawk (Mark Rendall) is being brainwashed by his captors.

Dr. Massey (Bill Pullman) and Sister Jo (Natascha McElhone) translate the secret book they found hidden in the puzzle box, which leads them to Tiberias on a mission to find young Hawk (Mark Rendall) and stop the impending birth of the Anti-Christ. Haden (Michael Massee) and Dr. Massey enter a final showdown in the dramatic conclusion.
