Dee Harris was at the height of her career as an investigative journalist when she became fixated on Celestial's Door, a secretive cult whose leader gave her an interview that millions watched. The locals near the compound spoke of strange activity in the surrounding area. Dee ignored every warning and went to the compound anyway, determined to uncover whatever the group was hiding. She has not been seen since. The police have found nothing. Her husband, driven by love and fear in approximately equal measure, takes on the investigation himself — entering the compound, searching the grounds, and confronting whatever has been happening inside.
