Brenda must fight for justice for two Russian prostitutes murdered by the illegitimate son of a Russian mafia figure whiles she overcomes the prejudices of a department who sees one dead prostitute as pretty much the same as another. As she does, she confronts her own prejudices, and discovers the justice for these women is scarce in a world dominated by men. When the FBI steps in to take over the investigation, she shows the stern stuff she's made of, using highly unorthodox methods to finally bring the murderer to an unusual form of justice. Meanwhile, Brenda's relationship with Fritz takes a new direction, as the FBI's involvement in this case hints at the challenges that will come when they must balance their work and professional lives. At the end of the episode, Brenda purchases one of the dead girl's house, and finds herself the owner of a cat she doesn't want, but who has ideas of its own.

Brenda and the Priority Homicide Team investigate a sniper who is killing gang members in and around MacArthur Park. Offering assistance is an ex-Army colonel who believes the sniper to be his son. As an all-out gang war looms, Brenda tentatively accepts his assistance, but as her investigation progresses, Brenda's doubts about the Colonel's motives grow. With Fritz' assistance, she realizes the Colonel is not there to help, but to help his son escape. The two face off in the dark on a Los Angeles rooftop, leading to an unexpected outcome. Elsewhere in the story, Sanchez' prior service with the Rampart Division CRASH gang squad allows him to play a pivotal role in the investigation as he briefs the squad on gang activity in the area, goes undercover as a gang member and assists with interrogations. Brenda's tense relationship with Taylor seems to relax, then abruptly grows tenser when a stake-out goes wrong. Gabriel becomes increasingly loyal to her, but Flynn and Provenza continue to resist her methods, dubbing her "Miss Scarlett."
