"Dis joint is based on some fo’ real, fo’ real s---," the title card to BlacKkKlansman reads.

BlacKkKlansman, Spike Lee’s latest film, tells the tale of a black detective in the Colorado Springs Police Department who infiltrates the Ku Klux Klan between 1978 and 1979. The detective, Ron Stallworth, strikes up a phone friendship with the local chapter of the Klan and with David Duke himself to discover and thwart cross burnings and a bombing.
