Gordon and Bullock search for the source of a new street drug storming the streets of Gotham that causes euphoria then death. Meanwhile Oswald Cobblepot works his way deeper into Maroni's (guest-star David Zayas) inner circle and Fish Mooney continues her plot against Falcone.

With Amsterdam running full-tilt, Carver and Truck discover there really is no honor among thieves. Prez impresses the detail with what he's found out from Bodie's cell phone, information that sends McNulty and Greggs on a road trip. Colvin sees the benefits of his plan working, but has overlooked the human toll, until the Deacon points out the deficiencies. Stringer Bell fumes over the cost of being a developer, as state Senator Clay Davis attempts to cool him off with some easy money, and then delivers on his promise of a federal housing connect. Carcetti confronts a hurdle he must clear if he wants to run for higher office, while Marlo appears to take the bait set by the Barksdale crew. Cutty is shown the possibilities for the future with a tour of a working gym, while the Western District cops toss back a few and weigh the merits of Amsterdam and their loyalty to their commander. Brianna and McNulty sit down for a heart-to-heart, while Avon dispatches the troops to track Omar and wrestles with a revelation by Stringer.

Although he tells Sydnor the Davis investigation could be a 'career case,' Freamon keeps a wary eye out for Marlo, who takes care of some unfinished business and strikes a business deal with Barksdale. Carcetti throws the police a bone by removing the cap on secondary employment, sending the detectives into fantasy-job reveries. With an eye on the state house, Chief of Staff Steintorf tries to find good news for the mayor while blaming the Royce administration for the Campbell revelation. Davis turns to Burrell for help with his problem, but the commissioner's hands are tied. At the newspaper, Executive Editor Whiting outlines a Pulitzer-worthy series in broad strokes, trumping Haynes while liberating the ambitious Templeton. Fed up with broken-down cars and unsolved serial murders, McNulty decides to take matters into his own hands.
