Sgt. Wayne Jenkins gives a lecture to cadets, while investigators Erika Jensen and John Sieracki question Momodu Gondo about his connection to a known drug dealer. Attorney Nicole Steele looks into complaints against notorious cop Daniel Hersl. Then, after an overdose death in Hartford County, David McDougall tracks the source of the drugs to Baltimore.

Jensen, Sieracki, and U.S. Attorney Leo Wise prepare to charge the officers of the GTTF. Suiter feels the distrust of Baltimoreans as he works a homicide scene and begins to sense that his past is closing in on him. Steele and Davis seek support from Baltimore’s new mayor on the consent decree before the new administration takes over the DOJ.

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.
