The documentary, which will be released in theatres on October 19, traces the rise and fall of the infamous Harlem drug lord during the heroin epidemic of the 1970's. The film's name derives from the headline "Mister Untouchable" that accompanied Barnes' photo when he appeared on the cover of The New York Times Magazine in 1977, followed by the sub-text that read "This is Nicky Barnes. New York police say he's the biggest drug dealer in Harlem. But can they prove it?"
