Unlike the previous Omen films, the adult Damien is now entirely aware of his unholy lineage, and his destiny.An alignment of the stars in the Cassiopeia region of the night sky causes the generation of a 'superstar', described in the film as a second Star of Bethlehem.

However, one by one, Damien kills off all the priests (some in horrific circumstances) until only DeCarlo survives.Finally, in spite of Thorn's efforts, DeCarlo informs Reynolds that the Christ-child is out of his...
