The extraordinary true story of the black detective who goes undercover to investigate the KKK. In 1978, Ron Stallworth is the first black detective in the history of the Colorado Springs Police Department. In the local paper, he finds a classified ad for the Ku Klux Klan - and a P.O. box for interested enquiries. All he's expecting are some racist brochures and a few scraps of information about the white nationalist terrorists in his community. What he gets is a phone call inviting him to join the KKK. So he does. Launching an undercover investigation of incredible audacity, Ron recruits his partner Chuck to play the 'white' Ron Stallworth, while Stallworth himself talks to the Klan over the phone. During his months-long investigation, Stallworth sabotages cross burnings, exposes white supremacists in the military, and even manages to deceive the KKK "Grand Wizard" David Duke himself - dodging danger and reprisal at every turn... Black Klansman is an amazing true story and a rollercoaster of a crime thriller; a searing and timely portrait of a divided America and the extraordinary heroes who dare to fight back.
