Secret societies have operated in Detroit for most of the city's history. Many started for fun and companionship. Others had more serious ends in mind. The African American Mysteries: The Order of the Men of Oppression helped enslaved people escape the South for freedom in Canada.

Join Bill Loomis in this fascinating look into the secret world of these groups.
