The Omen

When Kathy Thorn gives birth to a stillborn baby, her husband Robert hides the truth and replaces his son with an orphan boy, unaware of the child's satanic origin. The horror begins when, on Damien's fifth birthday, his nanny unexpectedly takes her own life. A priest who tries to warn Robert of the danger he is in dies in an unexpected accident. The growing number of deaths finally makes Robert realize that the boy they have adopted is the Antichrist, and that he must be killed to prevent a terrible prophecy from coming true.
