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.
