Sean Suiter is assigned to a new murder case, McDougall links with Scott Kilpatrick to take their case to the Feds, and Steele hears from Hersl’s vocal critics.

Jensen monitors Gondo’s calls, Steele speaks with BPD’s new police commissioner Kevin Davis, who admits to his precarious position. Meanwhile, a younger Jenkins struggles to fit in and brings Suiter along on a raid.

Jenkins pivots after a high-speed car chase yields no drugs. During his interview with the Feds, former officer Maurice Ward recalls how Jenkins remained unscathed as the GTTF’s supervisor – despite a series of illegal incidents. Steele confronts Davis about a list of cops who lied in court, and the city is rocked by the Freddie Gray protests.

Jensen, Sieracki, and U.S. Attorney Leo Wise prepare to charge the officers of the GTTF.

After the arrest of several GTTF officers, Suiter grows concerned about his grand jury subpoena. Jenkins learns his fellow officers are cooperating with the investigation as the full extent of his crimes comes to light. Davis and the mayor’s office go head-to-head on funding for the consent decree, while Steele questions whether the U.S. justice system can ever be changed.
