Roland "Prez" Pryzbylewski takes his second class of the day. He sets them a problem requiring division of apples between people. Randy Wagstaff is distracted by his classmate Calvin. Prez asks Calvin the answer and Calvin guesses correctly. He explains his rationale to the class: When refering to the possible answers, Prez tapped the correct answer several times, leaving chalk marks around it.
After school Randy walks home with Michael Lee and his younger brother Bug. Michael quizzes Randy about how he was able to return to school and Randy keeps quiet about his involvement with the police. Michael warns him about getting involved with authority figures. Randy tells him it doesnât matter as his foster mother, Miss Anna, now has him on a short leash. Michael points out that Randy is lucky to have a leash at all.
The next day Prez takes his class through their state mathematics test. Calvin and Charlene struggle with the change in the particulars from their practice work but Duquan "Dukie" Weems is able to apply the skills he learned to the new problem. When he tries to explain it to Charlene she storms out of the classroom.
Meanwhile Colvin continues his discussion of what makes a good corner boy with the special class. Namond and Kwame are emphatic about the need to prevent your people stealing from you because otherwise their thieving will spiral out of control. Zenobia Dawson is insistent that a beating for anyone caught is the way to prevent stealing. Darnell suggests that proof is needed before a beating; instead he suggests making the worker pay you back and if they complain, you know they are stealing. Colvin asks why the beating is necessary and Darnell and Markeith tell him that someone is always watching on the street and you cannot appear to be weak.
Namond tells Randy and Michael about the discussion on their way home from school. Michael asks Namond if he is coming to the gym and Namond tells him he has to work on selling off the rest of his package. Dukie remains in class after school playing on the computer. When De'Londa Brice catches her son Namond working on his package in his bedroom she angrily tells him that the police could seize their house if the drugs are found there and insists he hand the task on to a lieutenant.
Michael gets home to find that his mother has sold his groceries for drug money. He gives her just ten dollars when she tells him she is going out and she threatens to take the DSS (Department of Social Services) card from him. He calls the bluff and insists on keeping the card. When Michael gets home from the gym, Bug tells him that his father has returned. Michael is dismayed and repulsed when the man goes to touch him. He shares a disbelieving glance with his mother. Michael confronts his mother, telling her that she has broken her promise by allowing Bugâs father to return. She is unconcerned and tells Michael that things are going back to the way they were. Michael is stunned and she tries to comfort him by saying that people change. She tells Michael that Bugâs father will now hold the DSS card.
In class the next day an energized Namond raises the hypocrisy of a system that promises to reward him for good behavior when it fails to live by its own rules much of the time; he states steroids, liquor, cigarettes and Enron as examples. Darnell points out that even Colvin's police work focused on drugs, so in a way, drugs paid Colvin's salary. Zenobia claims that the street life is just part of the larger system.
Prez discusses his class's difficulty with the test with his colleagues. They reassure him that performance is low across all subjects. Mrs. Hanson and Mrs. Shapiro tell him he must follow the curriculum. Mrs. Grace Sampson tells Prez to spend some time teaching the test and some time teaching more accessible subject matter. Ms. Hanson offers typical sage advice: Prez's first year as a teacher has to be less about the children and more about him surviving.
At lunch, Prez watches Dukie show Crystal Judkins and her friends how to shop for jewelery on the internet. He notices that Michael is despondent at the back of the class. Prez asks if Michael is okay but Michael hesitantly declines to confide in him. Prez leaves his offer open and suggests that Michael could talk to the school social worker. Michael goes to pick Bug up after school but learns from his teacher, Miss Ella, that his father has already taken him. Michael runs out of the school after them. He finds Bug doing homework with his father and insists that Bug stay away from him.
Parenti, Colvin and the special class teacher discuss their progress. The academics are impressed with their results but have noticed that some of the children are not participating â those with deeper problems in particular. The teacher has seen signs of Oppositional Defiant Disorder and believes that Chandra has real psychological problems. Parenti wonders whether they can convince the corner kids to take an interest in subjects beyond drug dealing.
Namond gives his package to Kenard and tells him that he is a lieutenant and warns him not to cheat him on the profits. Namond delivers his takings to his mother and she notices that he has made less than she would expect from a full package. He blames his territory and she (despite his protests) leaves to convince Bodie Broadus to give Namond better territory.
Sergeant Jay Landsman briefs his squad before their shift. He introduces them to Tommy Carcetti, who will be observing them. He also announces the death of Colonel Raymond Foerster and his wake that evening. Bunk Moreland, Lester Freamon, Kima Greggs, Ed Norris, Vernon Holley and Mike Crutchfield are all present for the briefing. When Carcetti finishes the coffee in the breakroom Greggs angrily insists that he make another pot. She is still hostile towards Carcetti because of the political interference in the Braddock case. Carcetti asks the detectives to continue as usual. Greggs, Freamon and Landsman immediately stop pretending to work.
After the briefing Bunk tries to convince Holley and Crutchfield to revisit the scene of the shooting for which Omar Little has been arrested. He finds their witness, Old Face Andre, shady. They remain resistant to his efforts to get them to reopen the case. Carcetti approaches them and remarks on the caseload they face. Crutchfield insists they can handle it. Crutchfield continues the conversation in an interview room and becomes enraged with Bunk. As the three detectives talk, Crutchfield claims that Omar is no historical figure like George Washington Carver, rather he is just another petty criminal whose name rings up on multiple open cases including two of Bunk's. Crutchfield becomes more enraged with Bunks's attempts to go back on the case, thinking that he is doing so to discredit Crutchfield's clearance. After Crutchfield leaves Bunk appeals to Holley to look over the scene one more time.
At Foersterâs wake in the bar, Bunk is so drunk he runs outside to vomit. Upon returning, he is disgusted to find his old partner Jimmy McNulty drinking club soda. Cedric Daniels, Ilene Nathan and Rhonda Pearlman are also in attendance.
The next day Holley accompanies Bunk to Andreâs store. Holley asks Andre to retell the story for Bunk. Bunk finds it hard to believe that Andre would leave the bulletproof area when only threatened by a 9 mm handgun. As Andre is explaining that he was trying to save the delivery woman's life, Bunk notices the back door, stock inventory, and cameras that are a part of his store. Bunk then notices bullet hole from Omar's actual robbery and asks Andre about it â Andre claims the perpetrator wore a mask and he did not find time to report it. Bunk asks Andre to come in with them but he refuses. Outside Bunk claims that Andre's "whole story's fucked" as it makes no sense for Andre to have survived the robbery as a live witness. Bunk then states the store's main function is a "drug depot" having noticed the reinforced steel door, low inventory, and security cameras, and it would not make sense for Omar to first rob the store with a .50 caliber, a gun strong enough to shoot through Andreâs glass, and then come back a second time with a less powerful 9 mm. Finally, Bunk cites Andre's motive for lying; he wants revenge against Omar for robbing his stash. Holley is now convinced that Andre ran a con on the police.
Bunk returns to Andreâs store with a Grand Jury summons, finding him talking with a prostitute named Dee-Dee before bringing him in. Bunk and Holley then warn Andre that lying to the police is a much less serious charge than lying to the Grand Jury. The Grand Jury Prosecutor then tells Andre it's a ten-year minimum for perjury on the stand, and that the sentence is given "all the time," forcing Andre into retracting his story before he is even put before the witness stand. Bunk and Holley deliver the information to Landsman, who is enraged that he has lost a clearance to Bunkâs interference. Landsman also berates Holley for not standing up for himself.
Lieutenant Charlie Marimow pulls up his sergeant Thomas "Herc" Hauk having just received a harassment complaint. The complaint is from the woman who Herc was tricked into stopping at a train station. Marimow reprimands Herc in front of his subordinate Officer Kenneth Dozerman. He asks Herc for the source of the tip that led him to making his stop. Herc claims it was from a confidential informant. Marimow demands the source's name and Herc uses the non-existent CI â Fuzzy Dunlop (Herc has been illegally pocketing the payments made to "Fuzzy" since season two).
Herc and Dozerman make a traffic stop on Marlo. Herc insists that Marlo return his camera and Marlo promises nothing but takes Herc's card. After Marlo leaves, Dozerman urges Herc to come clean about the camera to Marimow. Herc persists in harassing Marlo hoping that he will convince him to give the camera back. He enlists the Western DEU squad in making a raid on Marlo's courtyard hangout. Next Herc stops Chris and Snoop. They hide their guns in an electric hidden compartment in their vehicle's dashboard but Herc finds their lime and nail gun in the trunk. He fires a nail into the pavement and tells them he wants his camera back.
Herc and Dozerman discuss their next move now that intimidation has failed. Herc remembers Randy's information about Little Kevin and suggests they look for him to get information on Lex's murder to get to Marlo.
Snoop and Chris casually deposit the bodies of two New York drug dealers in a vacant building, board it up and then go out for Chinese food. Later they teach some young Stanfield soldiers to kill on the streets.
Marlo delivers Hercâs card to Proposition Joe and Slim Charles. Joe promises to look into it and thanks Marlo for the work his people are doing driving away the New York drug dealers. Slim Charles suggests that Marloâs technique of disappearing the bodies of his soldierâs victims is lessening the impact of their kills. Marlo agrees to leave some bodies on the street.
Joe phones the police department and poses as a lawyer who needs to speak to Herc. He is transferred to Lieutenant Hoskinâs at the mayorâs security detail who tells him that Herc has been reassigned to the Major Crimes Unit.
Chris and Snoop hit the streets to find more New York dealers. Chris wants Snoop to ask the dealers a question about Baltimore; if they answer incorrectly, they will get shot. Chris suggests asking a question about Baltimore music, but Snoop is not familiar with the subject. When she almost kills a local dealer by mistake, Chris takes over asking the questions. Later, they find a New York dealer, and when he says he doesn't understand what Chris is asking, they shoot him, leaving his body on the street.
Chris and Snoop throw their weapons into the harbor after they are stopped by Herc. Chris also throws the nailgun in. Snoop tells him that he owes her money for the nailgun.
Tommy Carcetti continues his observation of the Baltimore Police Department at work spending the day in the Eastern District with the DEU squad. The shift lieutenant introduces him to a team of confident detectives at their morning briefing. They make their first arrest by enticing a man on his way to work to buy drugs for him. Carcetti catches up with the flex squad and finds that they are also making an arrest with little more than statistical value: a young boy they have pulled up for possession. The flex squad try to get the boy to give them information on a stash but he has nothing to tell them. The lieutenant seems positive about the work his men are doing.
Carcetti questions Deputy Commissioner Rawls about the unimpressive low-level busts. Rawls insists that he agrees with Carcetti and indirectly blames Commissioner Ervin Burrell, claiming that affirmative action policies sometimes advance black officers beyond their capabilities, and that a leader who owes his position to the "numbers game" of affirmative action would consequently care more about numbers -- such as arrest statistics -- than about genuinely reducing crime. Rawls claims that targeting high-end drug dealers would be his preference but that he respects the chain of command. Rawls admits that the BPD is "putting a bandaid on cancer" to fight the war on drugs and would be interested in leading the department into a different investigative strategy. After the meeting, Norman Wilson is offended by Rawls' "naked appeal to racial solidarity." Carcetti asks Wilson about Western District Commander Cedric Daniels, an African American officer in the department whom Carcetti views as a competent and good police officer. Wilson tells him that he does not have any political connections.
Assistant Stateâs Attorney Rhonda Pearlman visits Daniels at his office and finds him on the phone with Carcetti. Daniels tells her that Carcetti wants to meet with him to discuss what is successful in the police department. Daniels asks Pearlman how honest she thinks he should be. Pearlman tells him to be himself despite his worries that the mayor will not get rid of Burrell and Rawls.
Carcetti, Wilson and Gerry meet with representatives from the Democratic party to discuss strategy for his term. They hope to induce a drop in crime and build something in the downtown area with Carcetti's name on it. The party representative suggests that education is a good polling issue, but Wilson tells her that with the problems in Baltimore's schools Carcetti will be better off avoiding that topic. The party hopes that Carcetti will run for governor in 2008.
Carcetti meets with Daniels to discuss his concerns about the department. Daniels tells Carcetti that much of day-to-day police work in Baltimore is a waste of time, energy, efficiency, money and in some cases, talent. Carcetti reveals that Rawls has blamed Burrell's numbers game. Daniels doesn't buy it, but he refuses to discuss his superiors with Carcetti. He does point Carcetti towards Rawls gutting the Major Crimes Unit. Carcetti offers Daniels the CID Commander position under Rawls as a Colonel. Daniels asks Carcetti if he can trust him; Carcetti suggests they find out together.
Burrell visits Rawls to discuss trying to impress the new administration together. Rawls admits that he has been talking to Carcetti and Burrell acknowledges that Rawls is moving against him.
