Miles Lennon contacts Dorn after noticing stark similarities between a news story from Prague and cases he had previously investigated involving dead old men and greedy young brides. We learn of a potential honey trap ring operating across Europe: shortly after their marriage, each victim suffers a debilitating accident, leaving them reliant on their young wife's care. After our team becomes aware of an ongoing case in England, they discover the use of a nearly undetectable poison that is able to replicate natural deterioration. After interviewing a potential victim and his newlywed wife, they connect the suspect to a case in Prague. Ready to make the bust, they discover that both parties have vanished. The team is left with limited time - not only to save the life of a potential victim - but to catch the black widow gang before they disappear for good.
