In 1978 the community of Colorado Springs, Colorado experienced a growth of Ku Klux Klan (KKK) membership. One man dared to challenge their effort and thwart attempts to take over the city, Police Detective Ron Stallworth. He launched an undercover investigation into the Klan, gained membership into the organization, briefly served as Duke's bodyguard, and was eventually asked to be the leader of the Colorado Springs chapter. The irony of this investigation was that Stallworth is… A Black man. In the process he battled internal departmental politics to successfully pull off this "sting." Black Klansman explains how he overcame these obstacles and accomplished this almost unbelievable unique achievement.
