Lieutenant Cedric Daniels attends a meeting in Deputy Commissioner Ervin Burrell's office to account for the actions of his men in starting a riot in the tower buildings. When Daniels suggests that Detective Roland "Prez" Pryzbylewski should be restricted to office work, Major Valchek (Prez's influential father-in-law) insists this would be an admission of guilt. The other officers are more supportive. After the meeting, Burrell again insists on a simple investigation targeted at making arrests and seizures rather than spending time securing convictions against the organization's key members.
Bemoaning the lack of a photograph of the detail's main target, McNulty asks Detectives Augustus Polk and Patrick Mahone to get a photograph from the housing department of Avon Barksdale. This proves to be a dead end. Lester Freamon takes an interest when Greggs remarks that Barksdale used to box and once made Golden Gloves. The next day, he returns with a promotional boxing poster featuring a picture of young Avon Barksdale. Without saying a word, he returns to his desk and his dollhouse furniture. Daniels arrives, informing the detail that Prez is off the street and Herc is on sick leave for some time. McNulty visits his contact in the FBI, Agent Fitzhugh, with Greggs, looking to get some equipment to wire up Sydnor, who is being sent undercover. When McNulty tells Fitz that Daniels is the commanding officer, Fitz appears to bite his tongue because Greggs is present.
Detective Michael Santangelo is proven to be a mole in the detail, giving information to Rawls, and especially seeking (but not finding) anything to incriminate McNulty. Waiting around the detail offices, McNulty, Bubbles and Greggs discuss their relationships. Greggs tells McNulty that she's a lesbian and McNulty admits to being unfaithful, leading to his current separation from his now-vengeful wife, Elena. Sydnor arrives, in costume, but gets some advice from Bubbles on how to be more convincing. Together, Sydnor and Bubbles later visit the low rise projects, and Greggs photographs their activities. Sydnor notices with chagrin that neither drugs nor cash pass through the hands of any key players.
Back at the detail, Daniels reports that the commanding officers have insisted on fast "buy bust" style investigation to render some arrests and seizures. McNulty leaves the office angry that the case is being pushed in the opposite direction he had hoped for. He arrives at Rhonda Pearlman's home at 9 p.m. and asks how to clone a beeper. Pearlman suggests that he needs probable cause and to demonstrate exhaustion of other investigative techniques in order to get a signed affidavit from a judge. When he makes sexual advances, she remarks that their "dates" are not any better now that he's not married than they were before, but they end up in bed together anyway.
The following day, Daniels readies the detail to storm the projects in an effort to find a stash. McNulty refuses to participate in the action because he believes it will sabotage their case, and also refuses to sign off sick. Daniels is enraged at his perceived insubordination. In contrast, Det. Herc insists on aiding his co-workers despite being injured.
Later, Fitzhugh and McNulty have a meeting where it is revealed that the FBI has previously investigated Daniels for "integrity concerns". When the FBI found thousands of dollars of unexplained assets, they turned their findings over to Burrell, who has failed to take the investigation any further.
Omar Little and his gang spend several days in a white van watching the low-rise crew sell their drugs. D'Angelo Barksdale instructs Bodie Broadus, Poot Carr, and Wallace in showing respect to their customers and shares his belief that if there was no violence involved in their trade, then the police would not be interested in them. While waiting for more product to be delivered (waiting for "the stash" to be "re-upped"), D'Angelo spots them playing checkers with a chess set (pictured). He teaches them the game of chess using the analogy of the Barksdale crew - Avon as king, Stringer as the queen, the stash as the rook, soldiers as pawns. When Bodie learns of the possibility of a pawn becoming a queen, he draws a comparison with himself. D'Angelo is skeptical, remarking that pawns die early in the game, but Bodie insists that a smart pawn can be successful.
At Orlando's, Stringer is impressed by the amount of money D'Angelo is making in the courtyard. D'Angelo suggests that things will be better when they get a new package of narcotics. Stringer explains that there is nothing better on the way, but points out that if they sell a low-quality product, addicts will buy more of it, and the Barksdales will actually make more money. On his way out, D'Angelo strikes up a conversation with Shardene. She doesn't remember him but is open to his advances.
That night, back at The Pit, D'Angelo leaves to buy food just before Omar and his crew burst in to the stashhouse to steal the drugs. When the Barksdale dealers refuse to give Omar the location of the stash he shoots one of them, Sterling, in the knee. When his partner Brandon uses his name in front of the dealers Omar is exasperated. Bubbles is on hand to watch the whole proceedings and reports back to Greggs. The next day, Wee-Bey Brice berates D'Angelo for the theft of his stash while he was not even present. Bodie is able to report Omar's name to Wee-Bey.
Just at this moment, the detail arrives to arrest anybody they photographed previously. The dealers have changed stashhouses, so the detail finds little evidence, though Freamon notices a number written on a wall. While searching the crew, Detective Polk is punched by Bodie. Herc, Carver, and Greggs respond with a savage beating. Carver reports that a camera crew has offered to show their seizures. Daniels is disgusted when Greggs points out they have nothing to show.
