After a video of Brander arresting a drug addict is made public and turned into an abuse of power issue, the Mayor demands Mannion fire Brander, which he refuses to do since the man was found innocent. Instantly, a major riot breaks out in D.C., with the citizens protesting and attacking the police, demanding that Brander be fired for alleged police brutality. Several police cars are bombed and set on fire, and Nancy rescues an officer from an angry riot. He's badly injured and asks her out when he comes by to pick up his dog. Meanwhile, Temple witnesses his friend Reese die while trying to find the man who shot him. Mannion tries to save Brander, but he turns in his badge when he can no longer live with his guilt. Unfortunately, the mayor taped Mannion's conversation with Brander over the phone and fired him for obstruction of justice. Clive calls Mannion late at night, saying that Ella died unexpectedly.

Without a job and his best friend Ella, Jack takes off for Arizona to play some golf, but even without his badge, he can't stop solving crimes. He gets involved in a scheme of dirty cops with Mexican dealers and crosses the border to catch the dealer, which he does. Meanwhile, back in D.C., Cavanaugh and Sherry team up to trace Jack, and Cavanaugh discovers something that might save Jack's job. Nancy investigates on her own and finds that the guy that died on Brander's watch was injured before their encounter, which could clear Brander. Temple and Debreno set up a scheme with Cashmere Brown to bust Lester Richards, who is shot to death by Temple.
