A wave of urban reform brings down the notorious Franklin Terrace public housing towers, forcing the Barksdale drug crew to find a new home on the streets of west Baltimore.
Omar continues his bold strikes on Barksdale stash houses. As the wire on east Baltimore's Proposition Joe continues to yield little, a restless McNulty launches his own reinvestigation of D'Angelo Barksdale's prison suicide.
When a witness who testified against D'Angelo Barksdale is discovered murdered, McNulty and the detail take the opportunity to link the killing to Avon Barksdale's drugs crew.
West Baltimore residents get some surprising straight talk at a community meeting from Maj Colvin, Bubbles finds employment, and Bunk promises immunity to a group of corner boys in exchange for a little help.
Frustrated in his grass-roots reform efforts, Colvin arms himself with intelligence from Daniels' detail and personally delivers a message to the management.
