Now these deranged minds want her back and they'll stop at nothing. — Kidnapped and then imprisoned in a dank basement, Val is given a ghastly life or death ultimatum: Divorce her husband and bequeath his wealth to the cult or face losing Joel, and likely countless others, to a hideous death now lurking in a chemist's vial.
