A new movie from director Spike Lee has a premise that's almost impossible to believe.
It's 1978 and a black police detective in Colorado Springs, Colo., manages to infiltrate the Ku Klux Klan. He not only gets a membership card straight from Grand Wizard David Duke, but he's also asked to lead a local chapter because he's everything they are looking for — loyal, smart and a true believer.
He establishes a relationship with David Duke over the phone. And for meetings in person, he recruits a white co-worker to go in his place.
