Featuring rare footage and interviews with CIA insiders, this edge-of-your-seat documentary series traces the epic hunt for Osama bin Laden.

Unbelievable, untold missions from inside the world of espionage-told by the spies themselves. From real-life Jason Bournes to Bin Laden's take-down, each episode delivers cliffhanger-driven stories revealing the deadly work of the CIA.

Secret rituals. Blood oaths. Dark ceremonies. Fraternal orders. Around the world, and throughout history, secret societies have bubbled under the surface. In crypts and clubhouses, under lock and key, in the darkest corners of the internet, they assemble for mysterious purposes. Do they pull the levers of power or set out to destroy the ones in charge? What dark mysteries lurk behind closed doors; the sacred or the profane?

This series reopens the recently unearthed decades-old archive of renowned cryptozoologist Ivan Sanderson to reinvestigate his most compelling unexplained creature cases.
