Tipped off by the wire, Greggs, Herc, Carver and Freamon make a bust, but the incident makes Avon and Stringer suspicious, leading them to close shop in the Pit. Meanwhile, Bunk and McNulty look for another witness in the Gant slaying and hunt a suspect known as 'Mr. Bird.'

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.

Major Valchek gets back at Sobotka for the church gift fiasco and a feud begins, and Valchek ups the ante by asking Deputy Commissioner Burrell for a detail to go after Sobotka. Avon Barksdale continues to run his empire from a prison cell--counseling his nephew D'Angelo and going after a guard who is harassing the organization's convicted hit-man, Wee-Bey. On the waterfront, port police officer Beatrice Russell gets stuck investigating the contraband found in The Greek's container. McNulty lends a hand with the investigation, albeit for vindictive reasons. Ultimately, Detectives Bunk Moreland and Lester Freamon are assigned to help Russell investigate the deaths.

An unlikely source gives McNulty the tag of a car driven by Stringer Bell. Meanwhile, Greggs and Carver bust a congressional aide carrying dirty cash, but are forced to let him go. Later, Omar earns his 'loose cannon' moniker.

Season One finale. Every crew has weak links--including Avon Barksdale's. With the heat turned up in the high-rises, Daniels and McNulty turn to a higher authority in an effort to crack the case wide open.

Sobotka gives his lobbyist grief over the status of port legislation. Russell tells Sobotka the investigation is over, but a port computer is cloned, and when a container goes missing, the detectives follow. Simultaneously, Greggs and Prez tap into a circuit of Russian prostitutes. With two sets of evidence, the detail goes to Pearlman. Neither crime merits wiretap--but a drug connect could give the case legs. Rawls can't persuade Daniels to take the murders, but new evidence does. In the discordant Barksdale Empire, Bell tries to hold it together in the wake of a recent tragedy.
