Atlanta, 1950. Crime divides, the fight unites. Officer Denny Rakestraw and 'Negro Officers' Lucius Boggs and Tommy Smith face the Klan, gangs and family warfare in a rapidly changing Atlanta. Black families - including Smith's sister and brother-in-law - are moving into Rake's formerly all-white neighbourhood, leading his brother-in-law, a proud Klansman, to launch a scheme to 'save' their streets. When those efforts leave a man dead, Rake is forced to choose between loyalty to family or the law. Meanwhile, Boggs has outraged his preacher father by courting a domestic, whose dangerous ex-boyfriend is then released from prison. As Boggs, Smith, and their all-black precinct contend with violent drug dealers fighting for turf in new territory, their personal dramas draw them closer to the fires that threaten to consume Atlanta once again.
