Investigation Discovery honors the success of exposing double-dealing husbands and deceived wives in "Who the (Bleep) Did I Marry?" by reminding viewers to question the seemingly innocent people in their lives, from the dentist to the dry cleaner. The network's first true spinoff series, "Who the (Bleep)...," goes beyond stories of marriage misconduct to expose real evil lurking in relationships from all walks of life. Half-hour episodes include first-person accounts from those betrayed, among them Mary Capps, whose boss, Dennis Rader, was proven to be the infamous BTK serial killer, and Brent Jeffs, whose peaceful childhood turned hellish while living with his tyrannical, pro-polygamy uncle, Warren Jeffs. Re-enactments add to ID's signature methods of storytelling.
