In 1979 a priest at the Vatican sees a comet arching over the moon (described as the "eye of God"), heralding the birth of one chosen to be the mother of Satan's child. The priest is sent on a mission by the Pope to find and protect the girl from Satan, although a few Vatican knights (led by a corrupt cardinal) insist that she must die. In New York a newborn girl, Christine York, is identified by Satanists (including her physician, Dr. Abel, and her nurse and future guardian, Mabel) as the person chosen to bear Satan's child on New Year's Eve, 1999. The Satanists perform occult rites on the newborn.
