McNulty feels the heat when a witness who testified against D'Angelo is found murdered. Meanwhile, Greggs is given the lay of the land regarding Avon Barksdale's key players, and Herc, Carver and Prez find big-time trouble at the towers.

The early-morning 'field interviews' by Herc, Carver and Prez result in a minor riot, a boy losing an eye and some bad publicity for the department. On the other side of the law, D'Angelo teaches Wallace and Bodie how to play the game (chess) and later impresses Bell with his 'take' from the low-rises.

McNulty's detail finally gets 'clone' pagers to track Barksdale and his gang, but nobody can crack the codes used by the callers. Meanwhile, Bell instructs D'Angelo on how to school his lookouts while simultaneously flushing out a possible snitch. Later, Carver and Herc find Bodie, but their interrogation doesn't turn up results.

West Baltimore residents get some surprising straight talk at a community meeting from Major Colvin. Bubbles finds gainful employment; Stringer lunches uptown; and Bunk dangles the promise of immunity to a group of corner boys, in exchange for a little help. Greggs learns how Marlo takes care of business as Bubbles instructs her on the next big thing: disposable cell phones. Carcetti reveals his political ambitions and tries to enlist the help of an old acquaintance. The cops of the Western ride into the District for a roundup; Colvin delivers his plan to the corner boys, but they're not buying; and a frustrated Cutty opts to return to the game, welcomed back with open arms. McNulty reconnects with Stringer, but fails to connect with Pearlman, who's otherwise engaged.

Greggs and McNulty try to get Hardcase to turn informant as arraignment begins for those caught in the raid. Barksdale places a bounty on the head of rival gang leader Omar. Meanwhile, McNulty takes Bubbles on a cultural field trip, and Herc and Carver try to track down Bodie.

The low-rise pay phones are out of service, so McNulty and Daniels try to keep pace by tapping Barksdale's office. Bodie gets some new responsibilities from Stringer; Freamon gives Shardene a 'new look'; and D'Angelo goes to NYC on an errand for his uncle. With the detail's future hanging in the balance, Daniels faces off against Burrell and his political allies.
