All Prologue

When Omar is called into court, he identifies Bird and the weapon used to kill William Gant. As they observe the trial, Stringer discusses with McNulty whether Omar truly did witness the Gant murder. Levy subjects Omar to a harsh cross-examination, but Omar quickly turns the attacks back on Levy. After the jury returns a guilty verdict, Judge Daniel Phelan refuses Levy's request for an appeal bond and states that he will almost certainly sentence Bird to life in prison. Afterwards, McNulty asks Omar if he really saw Bird commit the murder. Omar responds, "You really askin'?".

Freamon tells Daniels that Frank lives within his means, while his stevedores union is in financial trouble. Freamon and Prez have found a paper trail through campaign finance records linking the union to $70,000 in contributions. Herc reports that they have had success making street level hand-to-hands, but have found no ties between portside drug dealers and the union. Beadie suggests that the union is making extra money by facilitating smuggling through the port. Daniels reassigns Prez and Greggs to focus on the vice trade, and Freamon works with Russell and Bunk looking at container movements.

McNulty visits his wife at her real estate office and she agrees to go on a date with him on Friday night. When they go to dinner, McNulty drinks only wine and lies to Elena and claims he's not drinking so much anymore. She says she's still angry with him but when McNulty asks for a chance to reunite with her, she invites him to bed instead. Later, over drinks, Bunk laments the pressure he feels from Rawls, while McNulty says he wants to make another go of things with Elena.

Greggs meets with Shardene Innes for help tracking down Eastern European girls working in the vice trade. She discusses her strip club assignment with Cheryl, who is angry that Greggs has returned to detective work and insists on accompanying her. A friend of Shardene's tells the detectives that there is a madam who organizes the girls and keeps them at a motel, where they are under guard when not working. After visiting the club, Greggs takes Cheryl to the port and explains how the Jane Does died. Beadie shows Bunk and Daniels how to track container movements on the computer. Beadie and Freamon are able to tie the missing containers to Horseface.

Nick asks Vondas for help in resolving Ziggy's problems with Cheese. Nick later tags along with Serge to the latter's meeting with Cheese and watches from the car as Serge and his associates draw guns on Cheese's crew. Serge then arranges a meeting in which Proposition Joe agrees to compensate Ziggy for the torched car. However, Joe makes it clear that Ziggy and Nick would both be dead if not for their association with the Greeks. Nick, Ziggy, and Johnny Fifty deliver the chemicals in exchange for drugs. Tempted by the additional payoff and Ziggy's pleas, Nick opts to take half the payment in cash and the rest in drugs. After a union meeting, Nick goes to the bar and gives Ziggy his compensation. Ziggy ostentatiously lights a cigarette with a $100 bill, causing Frank to leave in disgust. Outside, he asks Ziggy where he got his money and how he got his bruises.

Stringer delivers an envelope of cash to Leech, a contact from Washington, D.C., concerning a contract killing. Brianna visits D'Angelo and tries to persuade him to use Avon's set-up of Tilghman to shave time from his sentence. D'Angelo refuses, reminding his mother that she taught him to stand up for himself. He tells her to let him deal with things on his own and to take the fall for the Barksdale Organization. He then asks her to tell Stringer, Avon and Donette to leave him alone. D'Angelo passes Avon in the corridor and refuses to talk to him. While working in the prison library, D'Angelo is followed by an inmate named Mugs. Mugs garrotes D'Angelo with a leather strap, then ties it to a doorknob and places D'Angelo's hands in his pants, making his death appear to be the result of suicide.[1][2][3][4]

Omar Little's courtroom scene in this episode has been described as the character's "defining scene" and is among actor Michael K. Williams' favorites.[5]

The Futon Critic named it the ninth best episode of 2003, saying "There's simply been nobody like Omar (Michael K. Williams) on television before and he absolutely steals the show in this episode as he's called on to testify for the D.A.'s office. After being grilled by the defense for his less than moral activities, Omar responds with an amazing, funny and cheer inducing monologue about the legal system."[6]

The episode was also praised as a 'seminal moment for the series'. The tragic death of D'Angelo Barksdale was highlighted, with one reviewer stating that the episode drew on the show's 'incredible wealth of character and story background' to 'forge a powerfully emotional and meaningful episode'.[7]
