After two weeks on the job, the team still doesn't have a photo of their principal target, Avon Barksdale. Freamon has a solution when he hears Avon was a Gold Gloves boxer. In the aftermath of the near riot at the towers, Lt. Daniels stands by his men even though he thinks they were stupid to do what they did. He's ordered to lead a raid on the low-rise units in the projects but McNulty rebels and refuses to participate in a raid that's just being put up for show. Dissatisfied with the antiquated equipment they have to work with, McNulty asks his friend at the FBI to lend them listening devices. His friend also has some information for him about Lt. Daniels. D'Angelo isn't around when a gang led by someone called Omar robs his stash.

Detective Jimmy McNulty finds the body of a woman floating in the water while carrying out his new assignment of Harbor Patrol. Major Valchek has his gift to a local parish trumped by Frank Sobotka, his rival in the local stevedores union. And on the waterfront, a shipping container destined for 'The Greek' bakes in the sun with perishable cargo.

Major Valchek gets back at Sobotka for the church gift fiasco, and a feud begins. Avon Barksdale continues to run his empire from a prison cell. On the waterfront, Port Police Officer Beatrice Russell gets stuck investigating the contraband in the The Greek's container. McNulty lends a hand with the investigation.

Lt Cedric Daniels lets it be known he is going to leave the department. McNulty pursues the identity of the Jane Doe found floating in the harbor. A pair of young longshoremen, Frank Sobotka's son Ziggy and nephew Nick, heist a container and sell its contents, digital cameras, to men working for The Greek.

McNulty goes on a self-assigned moral mission to identify his floater, but his old partner, Bunk, says they have more pressing matter at hand: finding Omar to testify against a Barksdale trigger man in one of last year's murders. To placate Valchek, Burrell asks Daniels to lead the detail investigating Sobotka, and Daniels agrees.

Weak product in the pit has Bodie getting heat. Homicide detectives hand out grand jury summonses to stevedores involved in the homicide case, and Port Police Officer Beadie Russell works the lingering affections of an old boyfriend to find out how cargo disappears from the docks.

Bodie's disastrous sales efforts result in a tongue lashing from Stringer Bell. Ziggy pulls Johnny Fifty into a new caper that makes the Greeks pay big money. McNulty goes undercover in a brothel. As Valchek fumes over the change of targets and Burrell pulls the rug from beneath him, Daniels and Pearlman maintain their composure.

The detail uses satellite technology to its advantage. Bodie is unhappy that Proposition Joe's people are selling on his turf. Valchek visits the FBI in an attempt to get real results on the docks. Ziggy's deal with Double-G goes bad in a big way. Greggs considers motherhood and Prez makes a major blunder.

The detail makes a desperate move. Nick's deceit is in the open, as Sobotka is overwhelmed by bad news. The Greeks confidently ease out of a brief encounter with the detail and Omar's suspicions are validated. The detail hopes to find Vonda's boss. Nick hopes to repair relations with the Greeks and Sobotka is forced to make a difficult choice.

The detail has a setback. Russell and Bunk revisit Philly, looking for evidence. Brother Mouzone talks with Stringer Bell regarding their agreement, leaving Bell to contend with Avon Barksdale. McNulty and Greggs return to the Westside, where they discover new connections. Herc and Carver feel disrespected by fellow officers. Nick tries to come to terms with the Greeks, and himself.

After the notorious Franklin Terrace public housing towers are razed, the Barksdale drug crew searches for a new home on the streets of West Baltimore. McNulty and the detail look to make a case against Stringer Bell with a wiretap on a drug ring run by his ally, Proposition Joe. Daniels' promotion is derailed by City Hall due to his estranged wife's political ambitions.

Omar continues his bold strikes on the heavily guarded Barksdale stash houses. McNulty launches his own investigation into last year's prison suicide of D'Angelo Barksdale. On the streets the bloodbath continues, prompting Burrell and Rawls to jack up the heat on their district commanders. The street violence also presents Daniels with a tough decision. A beleaguered Cutty tries to get his life back on track.

The brutality at police headquarters continues over the perceived failure of department commanders to rein in the city's crime stats. Another hit by Omar on the Barksdale stash houses goes horribly wrong. Proposition Joe summons Stringer Bell to a meeting and tells him that the cops have screwed up. Daniels reassigns his detail after the wire on Stringer Bell goes dead.

Responding to an officer's call for help, McNulty and Prez turn up the wrong alley with unanticipated results. Cutty is surprised to find help from within Baltimore's power structure for his proposed boxing gym. Omar decides to go it alone against Avon Barksdale and Stringer Bell. Bubbles is wired up and sent into Hamsterdam

Herc's soft-duty job with the mayor takes an unexpectedly hard turn. Despite the potential damage to her career, Pearlman provides Freamon and Sydnor with subpoena ammunition for their 'grizzly bear' hunt in City Hall.

The ensuing negative attention turns Royce against Burrell, who takes the heat while Rawls comes to the rescue. At school, Prez's reward/punishment program meets with mixed results, and Colvin looks to restore order by separating disruptive "corner" kids from more attentive "stoop" ones. Chris tries to enlist Michael into Marlo's ranks, spooking Randy along the way. Dukie debunks Randy's "special dead" theory.

Poot returns to the corner after a stint in prison--and is welcomed back. Carcetti engages in a testy budget battle with City Council President Campbell, promotes Daniels, and hits a snag in his efforts to relieve Burrell of his duties.

After flexing his muscles around the city, Carcetti faces his first dilemma when a group of ministers protests Herc's mistreatment of one of their own. Randy gets the cold shoulder at school. Omar and Reynaldo pay a menacing visit to Proposition Joe, with their own proposition. Freamon has a revelation at a crime scene that promises to blow the lid off an unsolved mystery.

Carcetti's master plan for the police department is leaked to the press, sending the brass into a panic. Marlo turns to Proposition Joe to help with an enviable problem. Whiting and Klebanow drop a bombshell on the newspaper staff.

Carcetti maps out a damage-control scenario with the police brass in the wake of a startling revelation from Pearlman and Daniels. Their choice: clean up the mess...or hide the dirt.
