Omen IV: The Awakening (1991)

The antichrist is back, this time in the form of a little girl.  Faye Grant stars as the wife of an up-and-coming congressman who grows more and more suspicious about the less-than-angelic nature of their newly adopted daughter. The priest who baptized her mysteriously dies, the psychic fair she attends burns in a fiery holocaust and her nanny "accidentally" falls from a second-story window. Soon, Delia's mother begins to ask questions about the "coincidence" of these catastrophes. Her thoughts can't help but turn toward the biblical prophecy of Armageddon... the final confrontation between the forces of good and evil, beginning with the birth of Satan in human form.
