BlacKkKlansman (2018)

In this Spike Lee joint, we go back to the 1970s, where we find Ron Stallworth, the first black police detective working for the Colorado Springs Police Department.  In one of his first assignments after laboring behind the scenes to test the waters as a file clerk, Ron is hired to go undercover to record a speech being given locally by black activist Kwame Ture (Corey Hawkins), formerly known as Stokely Carmichael, at a nearby college, in which the subject is black empowerment, racist law enforcement, and preparation for the race war they feel will be inevitable. The police thought the speech would incite violence, but Ron saw the speech as just talk in that regard, and inspiring otherwise.
