The documentary tells the harrowing true story of William Bradford Bishop Jr., who in 1976 murdered his entire family in Bethesda, MD, and then vanished, never to be seen again. Was Bishop secretly working for the CIA, as a State Department co-worker surmised on the Today Show? Were the slayings premeditated, with others involved? Or was this a case of a seemingly successful man in a picture-perfect marriage who simply cracked one day? Has Bishop adopted a new identity in a foreign land? Or is he living off the grid somewhere in the States?
