Inside Secret Societies

Across six hourlong episodes, "Inside Secret Societies" explores some of the most clandestine and dangerous global underworld societies and their counterculture dogmas. The mysterious mix of hard-core gangs, fanatical religious groups, shady cults, esoteric societies and criminal fraternities -- all seeking to gain control of the world -- includes the Nazi party, the Ku Klux Klan, the Yakuza, the Order of Assassins, and the Brotherhood of the Blood.
