Thomas Dagget, a Catholic seminary student, loses his faith when he sees disturbing visions of a war between angels. Years later, Thomas is a detective with the Los Angeles Police Department. Two angels fall to Earth: one, Simon, enters Thomas' home and warns him of coming events, before disappearing. The second, Uziel, a lieutenant of the angel Gabriel, is killed in an altercation with Simon. Investigating the disturbance, Thomas finds in Simon's apartment the obituary of a recently deceased Korean War veteran named Colonel Arnold Hawthorne and the theology thesis about angels which Thomas himself wrote in seminary. Meanwhile, in Chimney Rock, Arizona, Simon finds the dead veteran awaiting burial and sucks the evil soul out of the body.The medical examiner informs Thomas that Uziel's body is like nothing he has seen before: it has no eyes, no signs of bone growth, hermaphroditism, and the same blood chemistry as an aborted fetus. Among the personal effects found on the body is an ancient, hand-written Bible, which includes an extra chapter of the Book of Revelation that describes a second war in heaven and prophecy that a "dark soul" will be found on Earth and used as a weapon.Unknown to Thomas, Gabriel arrives on Earth. Needing a human helper, Gabriel catches Jerry, a suicide, in the moment of his death and keeps him in a state of limbo. Unhappily dominated by Gabriel, Jerry retrieves Uziel's belongings from the police station while Gabriel destroys Uziel's body in the morgue. After finding Hawthorne's obituary, Gabriel and Jerry head for Chimney Rock. Before Gabriel arrives, at the local reservation school Simon hides Hawthorne's soul in a little Native American girl, Mary, who immediately falls ill and is taken care of by her teacher, Katherine.After finding Uziel's burnt body, all evidence of its oddity now lost, Thomas hurries to Chimney Rock. When Gabriel realizes Hawthorne's soul is missing, he confronts Simon. Gabriel says Hawthorne's soul will tip the balance to whichever side possesses it....
