John David Washington is Ron Stallworth, the first African-American police officer to join the Colorado Springs Police Departmant. Adam Driver is Flip Zimmerman, his more experienced colleague and eventually his partner. Together, they go undercover to infiltrate the KKK. Working as a team, they attempt to disrupt and take down the extremist hate group, lead by David Duke (played by Topher Grace). I’ll come straight out and say that this film taught us all kinds of things. not least how much we’ve missed dance-offs.
